Is this suited for github?

Yes, this is suited for github

Reproduction

Better auth 1.7.5 with drizzle adapter.

javascript

? The file ./auth-schema.ts already exists. Do you want to overwrite the schema to the file? › (y/N)node:internal/process/promises:394
    triggerUncaughtException(err, true /* fromPromise */);
    ^

[BetterAuthError: [# Drizzle Adapter]: The model "oauthResource" was not found in the schema object. Please pass the schema directly to the adapter options.]

Node.js v24.12.0

(sometimes I get this error too if I use v2-relations or I do some kind of switch up. It is hard to track)

javascript

This seems to only happen with the MCP plugin. I have tried with the regular oauth-proivder plugin and it works just fine.

javascript

    mcp({
      loginPage: "/sign-in", // path to your login page
      consentPage: "/consent", // path to your consent page
      resource: "https://api.example.com/mcp", // protected resource identifier
    }),
    cimd({
    	fetchClientMetadataResource,
    	metadataProfile: "mcp-2026-07-28",
    }),

Current vs. Expected behavior

For npx auth@latest generate to generate the actual schema. Now it just breaks/crashes
