I'm getting this error when doing a basic signup. Using SvelteKit. Auth Client: ```ts import { createAuthClient } from "better-auth/svelte" export const authClient = createAuthClient({}) ``` Auth: ```ts import { betterAuth } from "better-auth"; import { MongoClient } from "mongodb"; import { mongodbAdapter } from "better-auth/adapters/mongodb"; import { MONGODB_URI } from "$env/static/private"; const client = new MongoClient(MONGODB_URI); const db = client.db(); export const auth = betterAuth({ database: mongodbAdapter(db), emailAndPassword: { enabled: true } }) ``` Signup: ```ts const { data, error } = await authClient.signUp.email({ emailValue, passwordValue, nameValue, // callbackURL: "/" }, { onRequest: (ctx) => { }, onSuccess: (ctx) => { }, onError: (ctx) => { alert(JSON.stringify(ctx.error)); }, }); ``` I have confirmed that emailValue and passwordValue are accurate.
