Hello,

Is there a way to use it ? I followed the docs

Yes sure, like in the docs:

import { betterAuth } from "better-auth";
export const auth = betterAuth({
//… code above
    onAPIError: {
        throw: true,
        onError: (error, ctx) => {
            // Custom error handling
            console.error("Auth error:", error);
        },
        errorURL: "/auth/error"
    },
})

import { betterAuth } from "better-auth";
export const auth = betterAuth({
//… code above
    onAPIError: {
        throw: true,
        onError: (error, ctx) => {
            // Custom error handling
            console.error("Auth error:", error);
        },
        errorURL: "/auth/error"
    },
})

we've migrated from nhost and hasura and now in prod with better-auth, and we need custom pages for UX instead of the stock better-auth ones.
Currently, the errorURL doesn't work, not for OAuth callback and also not when throwing in model hooks.

import { betterAuth } from "better-auth"; export const auth = betterAuth({ //… code above onAPIError: { throw: true, onError: (error, ctx) => { // Custom error handling console.error("Auth error:", error); }, errorURL: "/auth/error" }, })
