MISSING_OR_NULL_ORIGIN

[Felix-Jorge-Flores]

Hello! Im having an issue, when i try to signIn.

I'm using a physical Android device (Poco X5 Pro 5G).

Versions:
Better auth: 1.3.34
flutter better auth: 0.1.3

How to reproduce:

1. Configure the server.ts file on better auth

  trustedOrigins: ['flutter://', 'http://localhost:3005'],

2. Deeplink

     <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="flutter" />
            </intent-filter>

3. Try to sign in with client.

 await client.signIn.email(
        email: event.email,
        password: event.password,
      );

I receive the error MISSING_OR_NULL_ORIGIN as in the next image.

I configured my trustedOrigins and my deeplink and doesn't work

I search for solutions and only disable origin check on better auth server works:

advanced: {
        disableOriginCheck: true,
 },

Hello, have you already add expo() from @better-auth/expo to your Better Auth server plugin ?
If yes, i will check it.

Hi. Yes, I've added the expo() plugin to my Better Auth server.
