Unhandled error in PlayFabUnityHttp: System.IndexOutOfRangeException when invoking /Client/GetPlayerStatistics

We are using the PlayFabUnitySdk.

Occasionally we get an error when invoking /Client/GetPlayerStatistics. We have updated to the latest SKD version, but the problem persists. The line that breaks is

bool isGzipCompressed = responseBytes != null && responseBytes[0] == 31 && responseBytes[1] == 139;

I assume the problem is that responseBytes is shorter than 2. I do not see how we can handle this error in any way, as it is internal to the SDK. Below is the ErrorMessage we get. Please advise.

Unhandled error in PlayFabUnityHttp: System.IndexOutOfRangeException: Index was outside the bounds of the array.

We had a similar case like yours, and the root cause was probably due to packet loss, please take a look at this thread:

https://community.playfab.com/questions/39877/indexoutofrangeexception-when-calling-updateuserda.html

Currently the SDK doesn’t handle this situation very well, as a workaround, you can add few Conditional statements above the line that breaks to avoid the exception when responseBytes is shorter than 2.

So basically we should throw the response away and hope for a better response next time?

Yes, that's right. You should have a retry mechanism when receiving invalid responses.
