Hello again. Thanks for all your help on this. Weâre still struggling to figure out what we might be doing wrong. The code works perfectly in the Unity Editor with the build target set to PC / Mac / Linux stand-alone, but not with WebGL as the build target (both as an actual build and in the editor).
What we see when we run with WebGL as the build target is the following:
- Two new records are created in the DB but are not updated or deleted.
- There is a NullReferenceException thrown on line 108 of UniversalWebClient.cs
- None of the Debug.Log($"***** âŚ") statements appear in the console (although we do see several WebRequest entries in the log).
Hereâs the final test code based on what you posted with just a few minor adjustments to the WebGL portions. (Also, to make the compiler happy, we had to put the MoralisLiveQueryController.cs and MoralisSubscriptionQuery.cs in the WebGL namespace):
Thank you!
