Steps to reproduce:

  1. Create new Unity project
  2. Add iOS and Android config files
  3. Update package names accordingly
  4. Import Firebase Analytics and Database
  5. Create script initializing Firebase app and database and attach to camera
  6. Run game in editor

How do I fix this?

Hi @michelleran, thanks for reporting this issue!

Can you answer a few more questions for me?

  1. does it work on your Android device or is it just broken in the editor
  2. if it does only break in the editor, does it break under all network conditions? Desktop support for Realtime Database is beta, and there are some corner cases not handled that usually result from corner cases around corporate firewalls.
  3. Try disabling the dll at "Firebase/Plugins/Mono/Firebase.Database.dll" and enabling the one at "Firebase/Plugins/Firebase.Database.dll". If this is successful, make sure that this hack doesn't live into your device builds, as this one will lend to a generally worse (slower) experience on devices.

For more information on what I suspect this is see bug #106 . Let me know if that helps (so I can mark this as a duplicate or see if it needs further investigation).

Hi @michelleran,

Have you tried running the unity database testapp in this repository? If not, try running it and seeing if you get the same error.

@alexames yep, same error (using .NET 4.x SDKs and Unity 2019.1.6f1).

@patm1987 it works on Android, as well as with Mono/Firebase.Database.dll disabled. I don't think it breaking in the editor is because of network conditions since I'm connected to a home network, which, as far as I'm aware, doesn't have any unusual configurations.

I do think that this is likely a duplicate of bug #106. The callstacks look the same and the same workaround seems to work for you. If you disagree, let me know!
