Manually verifying magic link token throws unexpected invalid_type

In my Expo mobile app, I'm trying to verify the magic link token manually as described here. But when I try to call the verify method with my token, I receive the following error:

{"code": "______CODE_INVALID_TYPE____EXPECTED_STRING____RECEIVED_UNDEFINED____PATH_______TOKEN________MESSAGE_REQUIRED__", "details": [{"code": "invalid_type", "expected": "string", "message": "Required", "path": [Array], "received": "undefined"}], "message": "[
  {
    \"code\": \"invalid_type\",
    \"expected\": \"string\",
    \"received\": \"undefined\",
    \"path\": [
      \"token\"
    ],
    \"message\": \"Required\"
  }
]", "status": 400, "statusText": ""}

{"code": "______CODE_INVALID_TYPE____EXPECTED_STRING____RECEIVED_UNDEFINED____PATH_______TOKEN________MESSAGE_REQUIRED__", "details": [{"code": "invalid_type", "expected": "string", "message": "Required", "path": [Array], "received": "undefined"}], "message": "[
  {
    \"code\": \"invalid_type\",
    \"expected\": \"string\",
    \"received\": \"undefined\",
    \"path\": [
      \"token\"
    ],
    \"message\": \"Required\"
  }
]", "status": 400, "statusText": ""}

and this is my code setup:

import * as SecureStore from 'expo-secure-store'
import { createAuthClient } from 'better-auth/react'
import { expoClient } from '@better-auth/expo/client'
import { magicLinkClient } from 'better-auth/client/plugins'

export const auth = createAuthClient({
    baseURL: process.env.EXPO_PUBLIC_API_URl,
    plugins: [magicLinkClient(), expoClient({ storage: SecureStore })],
})

auth.magicLink.verify({ query: { token: 'inserted_valid_token' } }).then((res) => console.log(res.error))

import * as SecureStore from 'expo-secure-store'
import { createAuthClient } from 'better-auth/react'
import { expoClient } from '@better-auth/expo/client'
import { magicLinkClient } from 'better-auth/client/plugins'

export const auth = createAuthClient({
    baseURL: process.env.EXPO_PUBLIC_API_URl,
    plugins: [magicLinkClient(), expoClient({ storage: SecureStore })],
})

auth.magicLink.verify({ query: { token: 'inserted_valid_token' } }).then((res) => console.log(res.error))

I can verify that we're actually sending a token as string. Anyone has any idea perhaps? Thanks!

Retrieving session after magic link signin in Expo

Hi guys, We've set up Better Auth server in our nextjs app and created a successfull authentication setup. Now we're trying to use that same setup for our login on our Expo mobile app. For both the platforms we use a magic link. I've followed the setup here: https://www.better-auth.com/docs/integrations/expo with a custom server. I've managed to create a succesful login and deeplinking in the app based on the callback url looking something like this: http://localhost:3000/api/auth/magic-link/verify?token=super-secret-token-here&callbackURL=exp://192.168.1.60:8081/--/customer/(tabs)/home But when the app navigates to that screen and I call auth.useSession(), the session is always null. Does anyone have a clue on what I'm missing? "@better-auth/expo": "^1.1.18", "better-auth": "^1.1.18", ``` database: drizzleAdapter(db, { provider: 'pg', schema: { user: schema.user, session: schema.session, account: schema.account, verification: schema.verification, }, }), user: { additionalFields: { activeCompanyId: { required: false, type: 'string', }, type: { type: 'string', }, language: { type: 'string', }, dateFormat: { type: 'string', }, timeFormat: { type: 'string', }, }, }, plugins: [ expo(), magicLink({ disableSignUp: true, sendMagicLink, }), ], trustedOrigins: ['*'], // ['exp://'],
