RCTBatchedBridge.m Error: Invalid data message - everything must be length:% zd. React Native, iOS Simulator

Question

I use react-native-oauth and get this error (see red image below) when trying to log in. I searched and found only this similar unanswered question . I looked at the source and found where the error was raised on line 954, and it looks like moduleIDs.count should equal methodIDs.count and paramsArrays.count :

  if (RCT_DEBUG && (moduleIDs.count != methodIDs.count || moduleIDs.count != paramsArrays.count)) { RCTLogError(@"Invalid data message - all must be length: %zd", moduleIDs.count); 

So, still in the source , I search for these objects and find them defined a little higher, on lines 943-945, and they use RCTConvert, whose functions "... everyone takes a JSON value as input and matches it with a native type or class Objective-C ". - React docs

So it looks like this is a transmission related and / or network error. But I have basically 0 knowledge in these areas, and I feel like I’m in a hurdle to investigate and wondered if anyone has any ideas to move forward. Being new to React Native and never doing any Objective-C can't help me.

Also, here my code generates errors.

 import OAuthManager from 'react-native-oauth'; import { Alert } from 'react-native' var env = require('../environment.js') const config = { facebook: { client_id: env.getKey("FB_ID"), client_Secret: env.getKey("FB_SECRET") } } const manager = new OAuthManager('myAppName') manager.configure(config); exports.authWithFb = () => { manager.authorize('facebook') .then(resp => Alert.alert('response!' + resp)) .catch(err => Alert.alert('error msg here: ' + err)); } 

I assume that this undefined error is related to the RCTBridge error, but not sure. You can see when I warn of the manager.authorize error. TypeError: undefined is not an object (evaluating 'fn') :

Edit:

When I try to notify the config object, I get a message that there is no way to reinforce it with a sub-object.

When you view the console in the chrome debugger, I get “Can't read the configureProvider property from undefined” and configureProvider() is what react-native-oauth , so it looks like the manager is not configured correctly, so, maybe i did well link the library. Check if the link works.

Im delving into errors a bit, and this seems like a promise / callback problem from NativeModules.OAuthManager . Accuracy: TypeError: Cannot read property 'authorize' of undefined . When I go into the stack trace, I find:

Any help is much appreciated, thanks.

Answer 1

So, for me, all that was wrong was the installation problem with react-native-oauth , because everything was fixed, since I returned to the point where my code had no other dependencies (I also had Firestack) and configured from scratching again, following reactions related to reaction-native-oauth. I realized that there was a step on the iOS / Xcode side that I skipped because when I initially tried, I could not find the file, so I just skipped this step:

From reaction-native-oauth readme

Then go to the next section, “Assembling phases” of the project parameters, find “Linking to the binary library”, expand it and click “+” to add libOAuthManager.a to the list.

The errors I received were removed from a few steps, but I am sure that it is somehow connected. Lessons learned: Do not try to do too many things at once and do not skip the necessary steps.

You will get this error when you send the wrong data to your home side. For example, if you must pass a string, but you pass an object.

Please console.log enter the config variable.

I think you sent the wrong data to your home side.
