iOS 15 : OperationsManager.removeOperation(cancelToken:) + 84 (OperationsManager.swift:43) #1574

Closed crawford-jake closed 2 years ago

crawford-jake commented 2 years ago

Description

We are getting reports of crashes from people using our app. The crash seems to occur when users have had the app open in the background for a very long time, but we also have reports of the app crashing after a short amount of time with the same error. From the log below, it appears amplify dereferences an invalid pointer. We have many other logs that all report the same crash in OperationsManager.swift. Additionally, this ONLY happens on devices running iOS 15. We have seen no issues on devices iOS 14 or lower, or on Android running the latest flutter amplify packages.

Additional Context

We are still attempting to create reproduction steps, however we are hoping the log above may help in determining a root cause.

Hi @crawford-jake thanks for reaching out. The stacktrace information is helpful but seems to suggest the operationsMap field in OperationsManager.swift is null - which shouldn't be possible. However, the code is called due to a apiError from FlutterGraphQLApi.swift. Would be interesting to know what this apiError is.

Until you are able to reproduce, can you tell us what Rest API methods you are calling and where in the code you make those calls?

The iOS stacktrace shows the following lines are crashing:

FlutterGraphQLApi.swift - 

 case .failure(let apiError):
      print("Subscription has terminated with \(apiError)")
      if !id.isEmpty {
          ==> OperationsManager.removeOperation(cancelToken: id)
      }

OperationsManager.swift - 

public static func removeOperation(cancelToken: String) {
        ==> guard let operation = operationsMap[cancelToken] else {
            return
        }

@fjnoyp thanks for the information, this helps a lot! We will be trying to recreate this error over the next few days. I will post here on what we find.

jamesblasco commented 2 years ago

We are also having this problem in our project with a different Stacktrace error. Currently this is happening for most of the users of our app using iPhone and iOS15 and it has become a very important blocker and priority internally

We found in the CloudWatch logs that our subscriptions are passing an "Operation: null".

subscription mySub($userId: String!) {
    getUser(userId: $userId) {
      myStuff {
        name
       }
    }
  , Operation: null,  Variables: 
{
    "userId": "123456"
}

@dnys1 Feedback from one of our cloud engineers: I started digging into amplify’s code, and since we get a null on removeOperation, that means that the operation is saved as a null when it is added. it gets added when we call Amplify.API.subscribe which executes this code and on line 161 its adding the operation (which is null) to a map.. so then on removeOperation when it gets the operation from the map, its getting a null value which means that createOperation on line 156 is returning null value.

We were able to crash the app by changing a lambda function to throw an error on a mutation. This crashed with the following:

Thanks, @crawford-jake - sorry for the inconvenience. We should have a fix out soon.

crawford-jake commented 2 years ago

@dnys1 Was this fix released in 0.5.0?

dnys1 commented 2 years ago

Hi @crawford-jake - apologies for the delay on this. No, we have not released it yet. We are planning a release with this and a few other fixes either today or tomorrow. Thanks for your patience!

dnys1 commented 2 years ago

Sorry again for the delay getting this out. It's been released with v0.5.1

Ekoios-Teddy commented 1 year ago

@dnys1 I have gotten same error with Ios version 14.2 and 14.3, the screen is frozen. But I'm testing on real device ios 14.7, 15.7, simulator version 16.1 it work. Please help me to find what happened and how can fix it. Thanks

dnys1 commented 1 year ago

Hi @Ekoios-Teddy, this is a slightly different issue. Can you confirm you have updated your iOS target to 13.0 in your Xcode project? If so, can you create a new issue with the reproduction steps?

Ekoios-Teddy commented 1 year ago

Yes, I have updated IOS target to 13.0 but it not work with any version Ios like 14.2 and 14.3 it not work.It work on 14.7 and 15.7 and 16.0.I guess maybe it will work with version greater than 14.5 or 14.7 but I can't check others version

dnys1 commented 1 year ago

Gotcha. Without more information, it's hard to say what the issue is. The stack trace shows the Hosted UI callbacks being triggered from a background thread. I'm not exactly sure how this would happen and haven't seen it myself. Would you be able to create a new issue with the steps to reproduce and a code sample which I can experiment with?

Ekoios-Teddy commented 1 year ago

Yes, i will create new issue about it. Humorously, it work with some version so i am not zoning this problem.
