@itssidhere, Can you provide how the data is being saved and retrieved using cloud_firestore ? Just a minimal code sample would be helpful.

[itssidhere]

Doesn't it looks like the cloud_firestore issue? @darshankawar

[russellwheatley]

Hey @itssidhere, it could be a cloud_firestore issue, but it might not be. We cannot understand the problem without a code sample repro. Please provide one and we can debug the problem.

[itssidhere]

@russellwheatley

Kindly have a look at this

I cannot reproduce it but I am just pointing out that something is going on

Related issues are

3354 which got resolved by adding an if statement. This exception is also coming from the same file i.e, FlutterFirebaseFirestorePlugin.java

[darshankawar]

@itssidhere, As requested earlier, we would need a minimal code sample on how you are sending and retrieving data from cloud_firestore, which will help us to debug the issue faster and better. Thanks

Hey @itssidhere. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

Since there haven't been any recent updates here, I am going to close this issue.

@itssidhere if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.
