Bug: the following peace of code breaks the parser

[Dmitry Nehaychik]

  protected validateToken(module: string) {
    return map((res) => {
      const token = this.getConfigValue('token.getter')(module, res);
      if (!token) {
        const key = this.getConfigValue('token.key');
        console.warn(`NbEmailPassAuthProvider:
                          Token is not provided under '${key}' key
                          with getter '${this.getConfigValue('token.getter')}', check your auth configuration.`);

        throw new Error('Could not extract token from the response.');
      }
      return res;
    });
  }
