Is this suited for github?

  • Yes, this is suited for github

To Reproduce

Set up two Next.js apps, both with better-auth.

One serves as an oidc provider (https://idapp.appname.local), with the oidcProvider plugin installed.
Here is the config:

oidcProvider({
        loginPage: "/signin",
        consentPage: "/consent",
        metadata: {
            issuer: "https://idapp.appname.local",
            authorization_endpoint: "/oauth2/authorize",
            token_endpoint: "/oauth2/token",
            jwks_uri: "/.well-known/jwks.json"
        },
        useJWTPlugin: true,
        allowDynamicClientRegistration: false,
        trustedClients: [
            {
                clientId: "clientApp",
                clientSecret: "xxx",
                name: "Client App",
                type: "web",
                redirectURLs: ["https://clientapp.appname.local/api/auth/oauth2/callback/idApp"],
                skipConsent: true,
                disabled: false,
                metadata: {}
            }
        ],
    })

The other serves as a consumer of the oidc provider (https://clientapp.appname.local), with the generic oAuth plugin installed.
Here is the config:

genericOAuth({
            config: [
                {
                    providerId: "idApp",
                    clientId: "clientApp",
                    clientSecret: "xxx",
                    authorizationUrl: "https://idapp.appname.local/api/auth/oauth2/authorize",
                    tokenUrl: "https://idapp.appname.local/api/auth/oauth2/token",
                    userInfoUrl: "https://idapp.appname.local/api/auth/oauth2/userinfo",
                    scopes: ["openid", "email", "profile"],
                },
            ]
        })

Current vs. Expected behavior

When you try to run the following code from the client app:

const { data, error } = await authClient.signIn.oauth2({
      providerId: "idApp",
      callbackURL: "/",
      errorCallbackURL: "/",
      disableRedirect: false,
      scopes: ["openid", "email", "profile"],
    });

You get the following error: oauth_code_verification_failed
Furthermore, in the console of the idApp, you get the following logs:

2025-10-02T15:34:27.784Z ERROR [Better Auth]: PrismaClientKnownRequestError Error [PrismaClientKnownRequestError]: Invalid prisma.oauthAccessToken.create() invocation: Foreign key constraint violated on the foreign key

What version of Better Auth are you using?

1.3.24

Backend

Auth config (if applicable)

Additional context

After some investigation, I noticed that the OauthApplications table in the database is empty.
Even after running npx @better-auth/cli generate followed by npx prisma db push,
the table is still empty.

It seems as if the trustedClients: object in the oidcProvider's config should automatically add these records to the database, but it does not.

Hi @pxtrickb! I'm Dosu and I’m helping the better-auth team.

This is expected behavior: trustedClients in the oidcProvider config are not automatically inserted into the oauthApplication table. They are used for runtime checks and consent skipping, but for token issuance, the client must exist in the database due to foreign key constraints. That's why you see the foreign key error when trying to sign in—the referenced clientId isn't present in the table.

To fix this, you need to manually insert your trusted client(s) into the oauthApplication table, matching the config fields (clientId, clientSecret, name, redirectURLs, type, etc). You can do this with a direct SQL insert, a Prisma create, or by enabling dynamic client registration and using the /oauth2/register endpoint. Once the client exists in the table, token generation will work and the error will disappear. This gap between docs and implementation is known and discussed in issue #4749.

Example Prisma code:

await prisma.oauthApplication.create({
  data: {
    clientId: "clientApp",
    clientSecret: "xxx",
    name: "Client App",
    type: "web",
    redirectURLs: "https://clientapp.appname.local/api/auth/oauth2/callback/idApp",
    disabled: false,
    metadata: JSON.stringify({}),
    createdAt: new Date(),
    updatedAt: new Date(),
  }
});

For more details and alternatives, see the docs and related discussion.

This gap between docs and implementation is known and discussed in [issue #4749](https://github.com/better-auth/better-auth/issues/4749#issuecomment-3307331347). Example Prisma code: ```ts await prisma.oauthApplication.create({ data: { clientId: "clientApp", clientSecret: "xxx", name: "Client App", type: "web", redirectURLs: "https://clientapp.appname.local/api/auth/oauth2/callback/idApp", disabled: false, metadata: JSON.stringify({}), createdAt: new Date(), updatedAt: new Date(), } }); ``` For more details and alternatives, see [the docs](https://github.com/better-auth/better-auth/blob/d1fe10962079c82920ea078a9847f65a59907b81/docs/content/docs/plugins/oidc-provider.mdx) and [related discussion](https://github.com/better-auth/better-auth/issues/4749#issuecomment-3307331347). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?

Trusted clients should be able to be added to the table and a skip consent option should be available.

Hi all, we released the new OAuth Provider Plugin which requires all clients to exist on the database and is cacheable with cachedTrustedClients. Feel free to let us know how it works :)
