Backend: Error: VM call panic: unexpected object with id c00e762742cf910938141c9647849974ef56ce9d:30 #97

I got that error after having a match stuck, trying to refresh the browsers to start over.

I believe this was related to 7da3a8d, as the panic seems to be an issue with realm storage and this panic seemed to occur in relation to that. If nobody has seen this anymore I think we can close this

Nope, confirming this still happens. (always with the same hash.) I don't precise steps to follow, though this seems to happen on LobbyJoin from time to time.

Some more information:

unexpected object with id is yet another unhelpful error message: it is called when store.GetObject cannot find the object with the given ID.
The hash c00... is the sha256 sum of gno.land/r/demo/chess. (see go doc gnolang.HashBytes; printf 'gno.land/r/demo/chess' | sha256sum).

This is the stacktrace I get:

'msg:0,success:false,log:--= Error =--
Data: &errors.errorString{s:"unexpected object with id c00e762742cf910938141c9647849974ef56ce9d:29"}

Since the GnoVM state seems to point to the execution of NewBoard, it seems to me there's a problem resolving defaultBoard, which might get deleted at some point in previous executions of the realm?

I'm going to make a PR to make it create a new value of Board, instead of attempting to re-use Board.

Found a way to consistently reproduce:

2023-09-25_08-43-40.mp4

Steps:

Make P1 and P2 join the lobby. Start a new game.
Play for a while. P1 resigns.
Make P1 and P2 join the lobby, again.
P2 gets the panic.

As I suspected, this is because we're reusing defaultBoard as a value.

PR fixing this incoming.
