Even after setting the scopes its not used while creating the redirect url
The default fallback is used always where offline_access is one of the scope which is not part of clerks scopes

You mention Clerk and Oauth?
I don't see that you're using anything oauth related in your auth config, also not sure how Clerk is related.
Could you fill me in?

<!-- gh-comment-id:2817160964 --> @amal-chandran commented on GitHub (Apr 20, 2025): - I was trying to use clerk as IDP based on these docs https://clerk.com/docs/advanced-usage/clerk-idp - As per the docs we need to create an oauth app for same thats how we can grab the client_id & client_secret - Then i used the same to register the sso provider - https://www.better-auth.com/docs/plugins/sso#register-an-oidc-provider - For my use case i used wrong approch as per the discussion - https://discord.com/channels/1288403910284935179/1363058816081723502/1363058816081723502 - The issue is still valid i think

@ping-maxwell commented on GitHub (Apr 20, 2025):

The offline_access scope is the standardized way to ask for refresh tokens. See the relevant OpenID Connect Core spec.

We can probably have some patch for you, but it feels like a loophole out-of-spec.
Ideally this should be fixed on Clerk's side.
@Bekacru wdyt?

@amal-chandran commented on GitHub (Apr 24, 2025):

You're right — the scope handling is currently missing, and Clerk should ideally handle that as part of the implementation.

There might be cases where some systems do not include all the standard scopes. In such scenarios, users should have the ability to remove or override certain default scopes.

From what I understand, if we correctly load the scopes provided by the user, everything should function as expected.

@handlebauer commented on GitHub (May 15, 2025):

I agree that upstream vendors should probably be handling the standard scopes better but I think better-auth would do better to give the user flexibility on this. You can configure the oidc_config scopes (via the sso_provider table) but it doesn't seem like those scopes are being respected currently (sends offline_access regardless because ctx.body.scopes is undefined). I don't have anywhere near full-context on this so I may very well be wrong about who should be responsible for what here but it's at the very least confusing as a consumer of this library.

This seems to be an issue, we need to be able to pass the scopes.
