React-native: NSInternalInconsistencyException: bundleURL must be non-nil when not implementing loadSourceForBridge

[varungupta85]

I am using react-native 0.31.0-rc.1. I am observing the error in iOS on Mac.

I recently update react-native on my app to the latest and started to get this error (detailed error below). This only happens when I try to run the app on the phone by using Option 2 which is to load using a static bundle. I have tried:

• Clean and rebuild in Xcode
• Reset cache and run react packager
• Uninstall the app on the phone
• Coming from Windows background, I have also tried to reboot my machine

Error in Xcode

I can see that this problem is printed here in the code but I am a beginner at best in native iOS development and don't know how to fix this problem.

Please help me in fixing this problem. Thanks!

Code in AppDelegate.swift file

/**
 * Loading JavaScript code - uncomment the one you want.
 *
 * OPTION 1
 * Load from development server. Start the server from the repository root:
 *
 * $ npm start
 *
 * To run on device, change `localhost` to the IP address of your computer
 * (you can get this by typing `ifconfig` into the terminal and selecting the
 * `inet` value under `en0:`) and make sure your computer and iOS device are
 * on the same Wi-Fi network.
 */
// let jsCodeLocation = NSURL(string: "http://localhost:8081/index.ios.bundle?platform=ios&dev=true")


 /**
 * OPTION 2
 * Load from pre-bundled file on disk. The static bundle is automatically
 * generated by "Bundle React Native code and images" build step.
 */
let jsCodeLocation = NSBundle.mainBundle().URLForResource("main", withExtension: "jsbundle")

print (jsCodeLocation)

let rootView = RCTRootView(bundleURL:jsCodeLocation, moduleName: "galarm", initialProperties: nil, launchOptions:launchOptions)

As you can see, I have commented out Option 1 and uncommented out 'Option 2. The jsCodeLocation is printed as nil. I have run the same app this way on the device like 100 times when I was usingreact-native 0.24.0`. I have not made any changes to the code and I started to see this error after the upgrade.

I have also asked this question on stackoverflow but since I was not getting any responses, I thought I will raise an issue here as well

I have the same problem ~

[varungupta85]

Please refer to the accepted answer for this question on stackoverflow. Looks like the IP detection for the ios bundle has been automated due to which the two options were removed and there is just one now.

@varungupta85 Thank you,I have resolved the problem follow your advice.

This url:
http://stackoverflow.com/questions/38780325/running-react-native-app-on-ios-device-using-offline-bundle

If you change to a release scheme while building your app, that will compile your app with the offline bundle.

Product > Scheme > Edit Scheme > set build configuration to Release

I sometimes get this error when using the development bundle (served by the packager).

Restarting the packager fixes it.

[gastonmorixe]

I solved by turning off WiFi in my mac and turning it on. Same on the iPhone.

[nevernet]

just using
jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"]; to instead of jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

this solved my problem.

[esutton]

None of these solutions worked for me when using:

        "react": "~15.3.1",
        "react-native": "0.37.0"

@nevernet had the best suggestion.

Go back to "old school" - it still works and I can debug again!

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  NSURL *jsCodeLocation;

  // Comment-out, cannot get past error: bundleURL must be non-nil when not implementing loadSourceForBridge
  //jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

#if DEBUG
  NSLog(@"AppDelegate:DEBUG");

#if TARGET_IPHONE_SIMULATOR
  NSLog(@"AppDelegate:DEBUG:TARGET_IPHONE_SIMULATOR");
  jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle"];
#else
  NSLog(@"AppDelegate:DEBUG:!TARGET_IPHONE_SIMULATOR");
  NSLog(@"To device debug, open RCTWebSocketExecutor.m & replace localhost with MacBook IP.");
  // Get dev host IP Address:
  //    ifconfig | grep inet\ | tail -1 | cut -d " " -f 2
  jsCodeLocation = [NSURL URLWithString:@"http://172.17.29.213:8081/index.ios.bundle"];
#endif

#else
  NSLog(@"AppDelegate:RELEASE jsbundle");
  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
#endif

  NSLog(@"jsCodeLocation = %@",jsCodeLocation);


  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"BluetoothConnect"
                                               initialProperties:nil
                                                   launchOptions:launchOptions];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return YES;
}

We were able to fix this without changing the jsCodeLocation code. It turns out that rn looks up the localhost ip either in the hosts file or because of the hosts file, I'm not good enough to read the Obj C to figure out exactly what its doing. I don't explicitly set localhost in our hosts files, as DNS will resolve it anyways, but because it isn't explicitly stated as 127.0.0.1 localhost, rn isnt able to grab the url of the device to store for offline bundle creation or interacting with the packager.

So the solution was to add the localhost line to the hosts file, and the error went away, without changing the scheme to release and without hardcoding the old jsCodeLocation code. I will say that it is also possible some people who do have the localhost line explicitly set in the hosts file may be having issues because the hosts file has been corrupted or is encoded incorrectly. I've read a bunch of places while hunting for the solution to this problem that osx fails to read the hosts file if it has those issues.

I've updated the so question here as well with what I've found http://stackoverflow.com/questions/38780325/running-react-native-app-on-ios-device-using-offline-bundle/40730709#40730709.

Still getting the same error. Tried all of it. Can someone help?

I got this when migrating a native project over to react native: check that the following is in your info.plist (right click it and edit as source).

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>

                <true/>
            </dict>

Note, i did not have to "Go back to old school" - i'm still using jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
