auth problem while setting up a socket

I'm looking to set up a socket for notifications.. I'm attempting to use the wasp documetation (0.15) and I'm getting an auth error , I'm unable to

webSocket: {
    fn: import { webSocketFn } from "@src/webSocket",
    autoConnect: true, // optional, default: true
  },

webSocket: {
    fn: import { webSocketFn } from "@src/webSocket",
    autoConnect: true, // optional, default: true
  },

import { v4 as uuidv4 } from 'uuid';
import { getFirstProviderUserId } from 'wasp/auth';
import {
  type WebSocketDefinition,
  type WaspSocketData,
} from 'wasp/server/webSocket';

export const webSocketFn: WebSocketFn = (io, context) => {
  io.on('connection', (socket) => {
    const username = getFirstProviderUserId(socket.data.user) ?? 'Unknown';
    // const username = 'testUser'; // For testing purposes, replace with actual user logic
    console.log('a user connected: ', username);

    socket.on('chatMessage', async (msg) => {
      console.log('message: ', msg);
      io.emit('chatMessage', { id: uuidv4(), username, text: msg });
      // You can also use your entities here:
      // await context.entities.SomeEntity.create({ someField: msg })
    });
  });
};

import { v4 as uuidv4 } from 'uuid';
import { getFirstProviderUserId } from 'wasp/auth';
import {
  type WebSocketDefinition,
  type WaspSocketData,
} from 'wasp/server/webSocket';

export const webSocketFn: WebSocketFn = (io, context) => {
  io.on('connection', (socket) => {
    const username = getFirstProviderUserId(socket.data.user) ?? 'Unknown';
    // const username = 'testUser'; // For testing purposes, replace with actual user logic
    console.log('a user connected: ', username);

    socket.on('chatMessage', async (msg) => {
      console.log('message: ', msg);
      io.emit('chatMessage', { id: uuidv4(), username, text: msg });
      // You can also use your entities here:
      // await context.entities.SomeEntity.create({ someField: msg })
    });
  });
};

and error I'm getting

[  Wasp  ]   Property 'auth' is missing in type 'AuthUser' but required in type '{ auth: MakeAuthEntityWithIdentities<Pick<{ providerName: string; providerUserId: string; providerData: string; authId: string; }, "providerName" | "providerUserId">>; }'.

Hi @ayo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The error you're seeing:

error TS2345: Argument of type 'AuthUser' is not assignable to parameter of type 'UserEntityWithAuth'.
Property 'auth' is missing in type 'AuthUser' but required in type '{ auth: ... }'.

error TS2345: Argument of type 'AuthUser' is not assignable to parameter of type 'UserEntityWithAuth'.
Property 'auth' is missing in type 'AuthUser' but required in type '{ auth: ... }'.

suggests a type mismatch between what getFirstProviderUserId expects and what is being passed to it. What’s Happening - The getFirstProviderUserId function expects a user object with a specific shape (likely UserEntityWithAuth), but socket.data.user is of type AuthUser, which does not have the required auth property. - This is likely due to a mismatch between the expected types in your Wasp version and the actual types being used in your code. How to Fix 1. Type Compatibility - In the official Wasp documentation, getFirstProviderUserId is used directly with socket.data.user, and this works as expected in the provided examples. If you are using Wasp 0.15, it's possible that the types have changed or are stricter. - You can try casting the user to the expected type, or you may need to update your usage to match the latest Wasp types. 2. Defensive Check for Authenticated User - If the user is not authenticated, socket.data.user may be undefined or not have the expected structure. You should check for this before calling getFirstProviderUserId. Example from Docs:

import { getFirstProviderUserId } from 'wasp/auth'

export const webSocketFn = (io, context) => {
  io.on('connection', (socket) => {
    const username = getFirstProviderUserId(socket.data.user) ?? 'Unknown'
    console.log('a user connected: ', username)
    // ...
  })
}

import { getFirstProviderUserId } from 'wasp/auth'

export const webSocketFn = (io, context) => {
  io.on('connection', (socket) => {
    const username = getFirstProviderUserId(socket.data.user) ?? 'Unknown'
    console.log('a user connected: ', username)
    // ...
  })
}

This is the recommended usage in the docs and should work if your types are aligned with the Wasp version you are using. If you are still getting a type error, you may need to cast the user or update your types. 3. Handling Unauthenticated Connections - If you want to disconnect unauthenticated users, you can do:

io.on('connection', (socket) => {
  const username = getFirstProviderUserId(socket.data.user)
  if (!username) {
    socket.disconnect()
    return
  }
  // ...
})

io.on('connection', (socket) => {
  const username = getFirstProviderUserId(socket.data.user)
  if (!username) {
    socket.disconnect()
    return
  }
  // ...
})

This approach is also discussed in the community and is a safe way to handle unauthenticated connections without throwing errors that crash the server [Discord support thread: WebSocket authentication]. Summary - Ensure your types match what getFirstProviderUserId expects. - Check for the presence of an authenticated user before proceeding. - If type errors persist, consider casting or updating your Wasp version/types. If you continue to have issues, please provide the exact Wasp version and the definition of your User entity, as there may be breaking changes between versions [Defining the Events Handler]. Let me know if you need more specific help! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @ayo, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

Looks like there's a mismatch between WaspSocketData and what getFirstProviderUserId is expecting @kapa.ai

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're correct—your error indicates a type mismatch between what getFirstProviderUserId expects and what is actually present on socket.data.user. From the official Wasp documentation, getFirstProviderUserId expects a user object that contains an auth field with identities, as described in the Auth Entities documentation. The socket.data.user object, as injected by Wasp into the WebSocket connection, should have this structure if the user is authenticated [Defining the Events Handler]. However, if you are seeing a type error, it may be due to a mismatch between the AuthUser type (which may not have the auth field) and the expected UserEntityWithAuth type. The documentation does not provide explicit type definitions for WaspSocketData or AuthUser, nor does it detail how to resolve this type mismatch directly. What you can do: - Double-check that your Wasp version matches the documentation you are following, as type definitions may have changed between versions. - If you are certain that socket.data.user contains the correct structure at runtime, you can use a type assertion to satisfy TypeScript, but this is a workaround and not a long-term solution. - If the structure is not as expected, you may need to adjust how the user is attached to the socket or consult the latest Wasp type definitions. Unfortunately, the knowledge sources do not provide a definitive solution for resolving this type mismatch, nor do they specify the exact types for WaspSocketData or AuthUser. If this is a blocker, you may want to open an issue or ask for clarification in the Wasp community.

also this is coming back as undefined console.log('logged in user:', socket.data.user); @kapa.ai

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- If socket.data.user is coming back as undefined, it means the user is not authenticated when the WebSocket connection is established. According to the Wasp documentation, Wasp automatically injects the JWT into the connection, and if it is present and valid, the server adds a user to the socket. If the JWT is missing or invalid, socket.data.user will be undefined [Defining the Events Handler]. Common reasons for this: - The client is not sending the authentication token (JWT) when establishing the WebSocket connection. - The user is not logged in on the client side. - There is a misconfiguration in how the WebSocket client is set up to send authentication. What you can do: - Ensure the user is logged in before the WebSocket connection is made. - Make sure the client is configured to send the JWT automatically. Wasp should handle this by default if you use its built-in WebSocket integration. - If you want to handle unauthenticated users, you can check for socket.data.user and disconnect if it's not present:

io.on('connection', (socket) => {
  if (!socket.data.user) {
    socket.disconnect();
    return;
  }
  // ...rest of your logic
});

io.on('connection', (socket) => {
  if (!socket.data.user) {
    socket.disconnect();
    return;
  }
  // ...rest of your logic
});

This approach is also discussed in the community as a way to handle unauthenticated connections gracefully [WebSocket authentication]. If you are still seeing undefined, double-check your authentication flow and ensure the client is properly authenticated before connecting to the WebSocket server. The knowledge sources do not provide more detailed troubleshooting steps for this specific issue. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @ayo, I seem to be having a bit of trouble.

@miho is the man for Sockets

We have an error in the documentation! It should be

const username = socket.data.user?.getFirstProviderUserId() ?? "Unknown";

const username = socket.data.user?.getFirstProviderUserId() ?? "Unknown";

The code that we have currently in the docs worked with an older Wasp version < 0.13.0
