Ionic 5 Facebook Login about facebook-login

[rdlabo]

This may not plugin issues. Please check appsecret_proof .
This is my worked code:

    return this.httpService
      .get<{
        data: IFacebook;
      }>(`https://graph.facebook.com/v5.0/me?fields=id,email,first_name,gender,last_name`, {
        params: {
          access_token: FacebookToken,
          appsecret_proof: appSecret,
        },
      })
      .pipe(
        first(),
        map((d) => d.data),
      )
      .toPromise(Promise);
