Internal error

[Mortis66666]

I have an error when I try to run the multiplayer game I'm working on, it's working at the start, but now it shows an internal server error.

Also, another problem, the web server doesn't show anything, only a black screen without gameplay (although it still works when I export it and upload to Codingame)

It would help if you could provide a link to the contribution

@Mortis66666 your game hangs on the first turn, you have an infinite loop in canGo, the same problem happens locally

@Mortis66666 on our production servers that canGo method can end up hanging because of this:

java.lang.OutOfMemoryError: Java heap space
	at java.base/java.util.LinkedList.linkLast(LinkedList.java:146)
	at java.base/java.util.LinkedList.add(LinkedList.java:342)

We'll be adding some extra details to the "internal error" message to make it clear when the problem comes from a timeout
