I’m getting this error when I try to use gotoScene

Runtime error  
 bad argument #-2 to 'insert' (Proxy expected, got nil)  
stack traceback:

 '\_listener'

I have a few scenes before this one, that transition fine. Does anyone know what would cause this error? I don’t want to post my code because it is quite bulky [import]uid: 208811 topic_id: 36969 reply_id: 336969[/import]

I would suspect that in the scene you are going to you have an error. And if I were a betting man, you’re trying to insert an image into your display group in that scene that doesn’t exist. Possibly a bad file name on a display.newImageRect() somewhere above it.

This is very strange! As far as I can remember I did no further work on my code after I posted this question yesterday. I am running the code now and I am no longer getting the error. How can this be? [import]uid: 208811 topic_id: 36969 reply_id: 145276[/import]

I came across this error again today in another scene. I discovered that, in the scene I was leaving I was either calling storyboard.purge/remove(“scene”) in the exitScene(). After I removed this it worked fine. I also have a question about memory management, Do I have to manually remove and nil out every table I use?

Year 2021,
I got same err…

I found that it happens if a display object is deleted and recreated again. It is better to hide such an object and show again, it gives no errors.
