Error Spam When Opening Project

[ptlthg]

I get the following two errors spammed in my console when opening my 4.2 project with asset placer enabled. I can't seem to reproduce these reliably, but these errors are printed every frame, so I've had to edit the code myself to stop them. (By adding a null check and a TryGetValue)

System.NullReferenceException: Object reference not set to an instance of an object.

Not sure if just adding checks is enough to fix it or if this is a symptom of a bigger issue, but I've had to replace dictionary lookups in the code for asset placer buttons with TryGetValue for the last couple of Asset Placer versions because I keep running into that error in particular.

Let me know if there's any more information you need, thanks

Hey, thanks for reporting and I'm sorry that you had these issues. As it seems you were able to fix it for now, I'll look into this when I'll work on the next version, but please let me know if something comes up again.

Hey @ptlthg I just uploaded AssetPlacer 1.2.2 which fixes at least the second issue you had. I have so far not been able to reproduce the first issue, so could you let me know, if it still appears with the upgrade, now that the initialization works properly?

Thanks for the update!

I just tried it out a bit more today. I'm not sure if it matters, but I left Godot running with the plugin in the background for a few hours and when I came back to it the same first error started spamming again in the console. The console tab was open while this was happening, and moved my mouse around to hit the clear console button also while this was still happening.

The second error hasn't happened again though, but I only used the plugin actively for maybe an hour, so I can't say for sure if it's gone.
