I integrated supabase with react-native I followed this article But I couldn't signUp

import AsyncStorage from '@react-native-async-storage/async-storage'
import { createClient } from '@supabase/supabase-js'
import { SUPABASE_URL, SUPABASE_ANON_KEY } from '../constants'

export const supabase = createClient(SUPABASE_URL, SUPABASE_ANON_KEY, {
  localStorage: AsyncStorage as any,
})

const signup = async (email, password)=>{
   const { user, error } = await supabase.auth.signUp({
        email,
        password,
    })
    if(error){
        console.log(error); 
        // Object {
        //  "message": "Unable to validate email address: invalid format",
        //  "status": 422,
        // }
        return
    }
    return user;
}

When I Invoke signup function it prints

Unable to validate email address: invalid format
