Better Auth Error Session data is too large to store in the cookie
I'm always getting this error whenever I tried to sign up.
```shell
SERVER_ERROR: [Error [BetterAuthError]: Session data is too large to store in the cookie. Please disable session cookie caching or reduce the size of the session data] {
cause: undefined
}...
Solution:
This occurs because the base64 of the profile picture is too large. You should upload the profile picture to a S3 bucket or cloudflare R2 and save only the id to the database / cookie

Next.js Hydration Error Linked to useActiveOrganization Hook
Hi, is it normal if I have a hydration problem when I use isPending from useActiveOrganization?
Since I added ‘isPending’ I get hydration errors when I refresh. It's possible to refresh the first time without getting the error, but on the second refresh it does.
I wrote this, which reproduces the bug perfectly....
how to return more data from `/get-session`

ended up fixing this by adding errorURL to my betterAuth for the onAPIError property

Guidance on JWT / Bearer usage for external APIs
Hi all, after some tinkering, I have JWT set up within a Nextjs app to use as a bearer token for an external api. The api uses the JWKS endpoint to validate the token. This works fine. I am looking for guidance of best implementation guidelines for security and performance. We heavily use server patterns in Next so we don't rely on nor use
authClient, just the server api.
At the moment, if I call auth.api.getToken, it issues a new token every time thus invalidating any fetch caching to the external api. I can store this token outside the request scope (variable or local storage) however this doesn't take into account expiration of the JWT token within decrypt it and checking timestamps on each request. While this works, I am wondering if there's a more efficient or more "betterauth" way of doing this. Perhaps the OIDC Provider is a better choice here?
To sum:...Expo Sign in with Apple: clientId vs appId vs serviceId vs bundleId ?!? 🤷
Trying to work through this: https://www.better-auth.com/docs/authentication/apple#configure-the-provider
It says:
On native iOS, it doesn't use the service id but the app id (bundle id) as client id, so if using the service id as clientId in signIn.social() with idToken, it throws an error: JWTClaimValidationFailed: unexpected "aud" claim value. So you need to provide the appBundleIdentifier when you want to sign in with Apple using the ID Token....
Solution:
I figured it out - the appBundleIdentifier has to be host.exp.Exponent when using expo dev
How to update `api/auth/get-session` with new session data?
I am updating the users table with the new name but accessing
api/auth/get-session gives the old data. Is there a way to trigger an update when the database is updated so session data is also updated?
I am using tanstack start. ```import { createAPIFileRoute } from '@tanstack/react-start/api'
import { auth } from '@/lib/auth'...Issue trying to convert to cloudflare workers

can Stripe's period_end be overwritten?
Stripe plugin and Sveltekit question. I am building an app where a free 7-day trial triggers on first log in using the better-auth stripe plugin. the period_start and period_end in the schema get correctly set on first login. When the user goes to Stripe.com to complete checkout, the period_start and period_end resets with a new timestamp so this could turn the 7-day free trial into a 14-day free trial if they complete the stripe checkout at the end of the first 7 days. I set trial_end to match...
Solution:
why not just only rely on
trail_end for the trail period and if have have non-trail subscription, you'll start usnig period start and end as a flag instead.subscription table is not generated
Following https://www.better-auth.com/docs/plugins/stripe#subscription guide and version 1.2.5
my auth looks like:
```
export const auth = betterAuth({...

Using the Stripe plugin, I have the subscription configuration:

Check GitHub organisation
Hello, is it possible to check what GitHub organisation someone is in with the GitHub social provider and limit logins based on that? Thanks in advance <3
Solution:
betterauth just maps only a few fields from the whole github profile response. you wouldn't get such details.

Trying to understand the connection between client and server in Tanstack Start
I've been exploring/experimenting with Tanstack Start framework. I mostly have the auth working, however I'm trying to understand why the
useSession hook is not working as expected (will not update when authentication happens, will update when logging out with the auth client).
Is there something I was supposed to do to connect the auth client with auth server (-side implementation)? Doc's seem to just indicate it should just work as-is....reset-password not working with email link
