bug: Error when trying to get multiplayer information using api
### Describe the bug

Access api.<domain>/v1/get_match?id=1.

An error occurs and an Internal Error is generated

### To Reproduce

Access api.<domain>/v1/get_match?id=1 

An error occurs and an Internal Error is generated

### Expected behavior

The premise was that one room could not call the api. room 0 should not have been created, but it was and could not be called from the api. when a second room was created, calling the room's id number 1 generated an error. English may be incorrect because of the use of translation software
