Failing to create session (Angular) on vercel.

export class AuthService {
  private readonly SESSION_KEY = 'user_session';
  private client: Client;
  private account: Account;

  private isAuthenticatedSubject: BehaviorSubject<boolean> = new BehaviorSubject<boolean>(false);
  public isAuthenticated$: Observable<boolean> = this.isAuthenticatedSubject.asObservable();

  constructor() {
    this.client = new Client().setEndpoint('https://cloud.appwrite.io/v1');
    this.client.setProject("PROJECT_ID");
    this.account = new Account(this.client);

  }

  async login(email: string, password: string): Promise<void> {
    try {
      //setting email session
      await this.account.createEmailSession(email, password);
      // const privatejwt : Models.Jwt = await this.account.createJWT();
      // console.log(privatejwt);
      // //settign json web token
      // await this.client.setJWT(privatejwt.jwt);
      const sessionData = await this.account.get();
      this.isAuthenticatedSubject.next(true); // Emit true when user is logged in
      localStorage.setItem(this.SESSION_KEY, JSON.stringify(sessionData));
      // localStorage.setItem('appwrite_jwt', privatejwt.jwt);
    } catch (error) {
      console.error('Login error:', error);
      throw new Error('Failed to login. Please check your credentials and try again.');
