"Can't determine position outside the location." Indoor Location

I’ve been trying to get the manual Indoor Location to work, although I’ve been having trouble with it. I followed the tutorial (http://developer.estimote.com/indoor/build-an-app/) and I got this error message.

failed to update position: Error Domain=com.estimote Code=1 “Can’t determine position outside the location.” UserInfo={NSLocalizedDescription=Can’t determine position outside the location.}

This is the code I’m using

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)viewDidLoad {
    [super viewDidLoad];
    
    // 4. Instantiate the location manager & set its delegate
    self.locationManager = [EILIndoorLocationManager new];
    self.locationManager.delegate = self;
    
    [ESTConfig setupAppID:@"AppIDHere" andAppToken:@"AppTokenHere"];
    
    EILRequestFetchLocation *fetchLocationRequest =
    [[EILRequestFetchLocation alloc] initWithLocationIdentifier:@"LocationIdentifierHere"];
    [fetchLocationRequest sendRequestWithCompletion:^(EILLocation *location,
                                                      NSError *error) {
        if (location != nil) {
            self.location = location;
            [self.locationManager startPositionUpdatesForLocation:self.location];
        } else {
            NSLog(@"can't fetch location: %@", error);
        }
    }];
}

-    (void)indoorLocationManager:(EILIndoorLocationManager *)manager
didFailToUpdatePositionWithError:(NSError *)error {
    NSLog(@"failed to update position: %@", error);
}

- (void)indoorLocationManager:(EILIndoorLocationManager *)manager
            didUpdatePosition:(EILOrientedPoint *)position
                 withAccuracy:(EILPositionAccuracy)positionAccuracy
                   inLocation:(EILLocation *)location {
    NSString *accuracy;
    switch (positionAccuracy) {
        case EILPositionAccuracyVeryHigh: accuracy = @"+/- 1.00m"; break;
        case EILPositionAccuracyHigh:     accuracy = @"+/- 1.62m"; break;
        case EILPositionAccuracyMedium:   accuracy = @"+/- 2.62m"; break;
        case EILPositionAccuracyLow:      accuracy = @"+/- 4.24m"; break;
        case EILPositionAccuracyVeryLow:  accuracy = @"+/- ? :-("; break;
        case EILPositionAccuracyUnknown:  accuracy = @"unknown"; break;
    }
    NSLog(@"x: %5.2f, y: %5.2f, orientation: %3.0f, accuracy: %@",
          position.x, position.y, position.orientation, accuracy);
}

I seemed to have the same problem the person in here did (https://forums.estimote.com/t/func-indoorlocationmanager-didupdateposition-position-is-not-invoked), although I’m not sure how he fixed his problem, someone suggested to move “[self.locationManager startPositionUpdatesForLocation:self.location];” into didViewAppear, when I did this, the error disappeared but then nothing happened, I didn’t get any output so the output was blank. I’m not sure what I need to do to fix this.
