[JimmyJMA]

Hello i got this error with firebase in my app :

Xcode version : 10.1
Firebase SDK version : 5.17.0
Firebase MLVisionText

Error :

F0325 21:33:09.189833 3 mobile_lstm_recognizer.cc:834] Check failed: codes.size() == 1 (2 vs. 1)

This app crash when the function of object vision "onDeviceTextRecognizer" is called.

Thanks you in advance for help

@JimmyMYnov Thank you for reporting the issue. Would you be able to share a sample project and steps to reproduce the issue, please.

[maksymmalyhin]

@JimmyMYnov Thank you for sharing this.
I was not able to reproduce the issue myself. I assume, there are some details I am missing.

Will it be possible to share your Podfile and Podfile.lock? Also, do you have the crash on a particular image? If yes, could you share it as well?

[maksymmalyhin]

@JimmyMYnov Another note - the most recent version of Firebase is 5.19.0. If you are able to update Firebase version and check the issue?

[JimmyJMA]

@maksymmalyhin

I missing that point : For two project i use carthage
This error is made with a camera, so no matter the picture.
I have already try to upgrade to 5.19.0 but this error is still same

And for details, i have this error since today, maybe an update in my environment ? For me it is a c ++ error so maybe the compilator ?

Are you calling FirebaseApp.configure() properly in AppDelegate? I had this problem too but realized I had removed FirebaseApp.configure()

[JimmyJMA]

Yes this error is happened and generalized in my app when i make an archive

@MestevMYnov Can you please provide a stack trace or log file that shows the error/crash?

@MestevMYnov Thank you! We can definitely locate where the error is coming from, but the error could happen for many reasons. Are you able to provide the full crash log, which will help us determine which code path is leading to this check failure?

I can't provide full crash log, because it's entreprise project. But only these line is pertinent, other log it is about layout constraint and other, no relation with Firebase

@MestevMYnov Please provide the stack trace (not the console log) where you've redacted your company's proprietary symbols. Firebase and UIKit symbols should remain in the stack trace.

This stack trace contains no information since the symbols aren't visible. Can you upload a sample that reproduces this issue?

Hi MestevMYnov, you mentioned that you can reproduce this with https://github.com/firebase/quickstart-ios/tree/master/mlvision. Could you provide detailed steps of how to reproduce this crash using the quickstart mlvision app, including any customization you might have made to the app, and any particular test image you have used for reproducing the crash? Thanks!

@morganchen12
Hello,

After testing, I can say that the bug comes from "./Carthage/Build/iOS/TextDetector.framework/GoogleMVTextDetectorResources.bundle".
I deleted the reference in "Build Phase" and added it again and it's work.

So now, for the moment i don't have this crash again, but where does he come from ??? I think the reference is broken or something else, but why this crash is not catched or logged ?

I think we need investigation
