log your error with error.stack to see the reason.

DeviumOP•3mo ago

would i need to extend a function to log the error in the [all] api route?

begot•3mo ago

should be able to use this https://www.better-auth.com/docs/concepts/hooks#errors

Hooks | Better Auth

Better Auth Hooks let you customize BetterAuth's behavior

DeviumOP•3mo ago

Like this?

// src/lib/auth.ts
import { betterAuth } from "better-auth";
import { prismaAdapter } from "better-auth/adapters/prisma";
import { PrismaClient } from "@prisma/client";
import { createAuthMiddleware, APIError } from "better-auth/api";

const prisma = new PrismaClient();

export const auth = betterAuth({
    emailAndPassword: {
        enabled: true,
    },
    socialProviders: {
        google: {
            clientId: process.env.GOOGLE_CLIENT_ID as string,
            clientSecret: process.env.GOOGLE_CLIENT_SECRET as string,
        },
    },
    database: prismaAdapter(prisma, {
        provider: "postgresql", // or "mysql", "postgresql", etc.
    }),
    hooks: {
        error: createAuthMiddleware(async (ctx) => {
            if (ctx.error instanceof Error) {
                console.error("Error hook stack:", ctx.error.stack);
            }
            // Rethrow the error so that the endpoint responds with the proper error.
            throw ctx.error;
        }),
    },
});

// src/lib/auth.ts
import { betterAuth } from "better-auth";
import { prismaAdapter } from "better-auth/adapters/prisma";

const prisma = new PrismaClient();

export const auth = betterAuth({

        }),
    },
});

sorry, i missed your other message - i haven't used the error hook myself, test it out and see if it behaves as expected.

DeviumOP•3mo ago

No worries, it still seems to output this without a full stack

could be because it's throwing ctx.error - i remember seeing this and resolving it by logging with .stack instead of throwing, can you temporarily log ctx.error.stack

bekacru•3mo ago

this is thrown from prisma. I think it's cause your Id fields are integer. Better auth expectes string Ids. If you really need to make them int instead, you'd need to disable generated Ids by setting advanced.generateId to false.

Ok thank you!
