I struggle so hard with API auth

I always get this when auth is set to true for an api. [ Server!] [VoiceAgentSession] Failed to initialize voice session: HttpError: Authentication required [ Server!] at _waspvoiceAgentSessionfn (/Users/jacobferrari/wasupupdate/my-saas/app/src/server/agents/apis/voiceAgentSession.ts:17:13) [ Server!] at <anonymous> (/Users/jacobferrari/wasupupdate/my-saas/app/.wasp/out/server/src/routes/apis/index.ts:702:14) [ Server!] at Layer.handleRequest (/Users/jacobferrari/wasupupdate/my-saas/app/.wasp/out/server/node_modules/router/lib/layer.js:152:17) [ Server!] at next (/Users/jacobferrari/wasupupdate/my-saas/app/.wasp/out/server/node_modules/router/lib/route.js:157:13) [ Server!] at <anonymous> (/Users/jacobferrari/wasupupdate/my-saas/app/src/server/utils/posthogSession.ts:47:39) [ Server!] at AsyncLocalStorage.run (node:internal/async_local_storage/async_hooks:91:14) [ Server!] at withPosthogSessionContext (/Users/jacobferrari/wasupupdate/my-saas/app/src/server/utils/posthogSession.ts:47:20) [ Server!] at Layer.handleRequest (/Users/jacobferrari/wasupupdate/my-saas/app/.wasp/out/server/node_modules/router/lib/layer.js:152:17) [ Server!] at next (/Users/jacobferrari/wasupupdate/my-saas/app/.wasp/out/server/node_modules/router/lib/route.js:157:13) [ Server!] at logRequestSizeMiddleware (/Users/jacobferrari/wasupupdate/my-saas/app/src/server/serverSetup.ts:156:3) { [ Server!] statusCode: 401, [ Server!] data: undefined [ Server!] } [ Server ] POST /api/voice-agent/thread 401 88.109 ms - 53 [ Server ] POST /api/voice-agent/thread 401 88.109 ms - 53 I've always dealt with this no idea what to do.

Hi @Zuck. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- When you set auth: true for an API in Wasp, it means that Wasp will attempt to extract the user from the JWT token in the Authorization header and make it available as context.user in your API handler. If the request does not include a valid JWT token, or if the token is missing or invalid, context.user will be undefined. If your API handler then checks for context.user and throws an error (as in your stack trace), you'll get a 401 "Authentication required" error. Here's a summary of what's happening and what you should check: 1. How Wasp Auth Works for APIs
- When auth: true is set, Wasp expects the request to include a valid JWT token in the Authorization header. - If the token is missing or invalid, context.user will be undefined, and your handler will likely throw a 401 error if it checks for authentication (which is the recommended pattern) Docs: Custom HTTP API Endpoints. 2. Typical Handler Pattern
Your handler probably looks like this:

   import { HttpError } from 'wasp/server'

   export const voiceAgentSession = async (args, context) => {
     if (!context.user) {
       throw new HttpError(401, "Authentication required")
     }
     // ...rest of your logic
   }

   import { HttpError } from 'wasp/server'

   export const voiceAgentSession = async (args, context) => {
     if (!context.user) {
       throw new HttpError(401, "Authentication required")
     }
     // ...rest of your logic
   }

This is correct, but it means the client must send a valid JWT token. 3. Common Pitfalls
- No Token Sent: If your client isn't sending the Authorization header, you'll always get a 401. - Invalid/Expired Token: If the token is invalid or expired, Wasp will not set context.user, and you'll get a 401. - CORS or Middleware Issues: If you have custom middleware or CORS misconfiguration, the request might not even reach the handler as expected GitHub Issue: CORS Error. 4. How to Fix
- Make sure your client is sending the Authorization header with a valid JWT token. - If you're testing with tools like Postman or fetch, manually set the header:

     Authorization: Bearer <your-jwt-token>

     Authorization: Bearer <your-jwt-token>

- If you are using Wasp's built-in client API, it should handle this for you if the user is logged in. - If you are not logged in, or the token is expired, log in again to get a fresh token. 5. Debugging Tips
- Add logging in your handler to check if context.user is present. - Check the network request in your browser's dev tools to see if the Authorization header is being sent. - If you have multiple tabs or sessions, be aware that a 401 in one tab can clear the token for all tabs due to shared localStorage GitHub Issue: Token Clearing. Summary:
You are getting this error because your API is protected (auth: true), but the request is not authenticated (no valid JWT token). Ensure your client is sending the correct Authorization header with a valid token. If you need the API to be public, set auth: false in your Wasp file for that endpoint, but then context.user will not be available. If you need more help, please share how you are making the request to the API and how authentication is handled on the client side. References:

Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?
