When starting our project in the Unity editor, the editor crashes. The error log shows

We could narrow it down to the call firestoreDB.Collection("l").Document(documentID).Collection("p"), where documentID is null.

While this should be checked in our code that documentID isn’t null before trying to access the document, the Firebase SDK should also handle this internally to not completely crash the editor.

We’re not using the Storage SDK.

I’ve taken a look at Firestore’s section of the Unity SDK and found several places where specifying null to methods will cause the Unity Editor to crash. I’m going to work on fixing these since crashing is highly undesirable and I’ll change the methods to instead throw ArgumentNullException.

I have no idea why SWIGRegisterStringCallback_StorageInternal showed up in the stack trace. That’s very odd. So I’m going to ignore it for now and fix the methods to fail gracefully when given null arguments.

Thanks @dconeybe for the fix. This should go out in 8.1.0.
