[iOS 14.4.2] Keep having "NSErrorFailingURLStringKey" about react-native-fbsdk-next

[mikehardy]

@thebergamo I made a "needs reproduction" label for things like this, also stops me from clicking on it but indicates there may still be something to learn here, just without a reproduction, what can we do?

I’ll try to dig it when I have some time and I’ll keep you updated 😉

Interesting. I didn't realize 14.4.2 was out until you mentioned it. I just updated my real iOS device to it and logged into my app via facebook to see if it would fail as you describe.

My login process runs this code:

  private static async getEmailForFacebookLogin(): Promise<object> {
    return new Promise((resolve, reject) => {
      const request = new GraphRequest(
        '/me?fields=email,name',
        null,
        (error: any, result: object | PromiseLike<object>) => {
          if (result) {
            console.log(
              'UserStore::getEmailForFacebookLogin - got result:',
              JSON.stringify(result, null, 2)
            );
            // @ts-ignore
            if (!result.email) {
              console.log('UserStore::getEmailForFacebookLogin - no email permission granted?');
              Analytics.analyticsEvent('getEmailForFacebookLoginFail');
              reject(new Error('email-permission-not-granted'));
            } else {
              return resolve(result);
            }
          } else {
            console.log('UserStore::getEmailForFacebookLogin no result?');
            reject(error);
          }
        }
      );

      new GraphRequestManager().addRequest(request).start();
    });
  }

and it successfully fetched the email via a graph request. So I'm not sure what's going on there.

That's using FBSDK ios 9.0.1 according to my Podfile.lock.

It appears 9.1.0 is out but I haven't tried it on a real device running 14.4.2 yet. I just kicked off a TestFlight build in my dev environment that will include 9.1.0 in order to see. I'll try to remember to post findings back here but if you do not see a post from you can assume it worked and I had some other higher priority thing going on (because, it worked...). If it broke you can be sure I'll be back here to triage :-)

Well I just found from where the problem comes. I have the Lockdown app installed on my iPhone which put the VPN iOS feature on. Then the Login to Facebook throw the connection error.

Not sure this is specifically related to react-native-fbsdk-next but so you know.

[thebergamo]

After you mentioned about VPN, it might be that your VPN is blocking Fb domain? Do you use any other app in your device that connects with FB? Or can you try to access the FB in general?

From the error it seems to be related to some network issue. I'm installing the newest version and will try to log into my app within my VPN to check also

EDIT
Even with VPN and newest iOS I could login normally with aforementioned versions

love it! thanks @mikehardy

Still missing reproduction, no activity. Can always reopen, but closing to clean issue list.
