I am playing on 1.15.2 but when I enter the Pin when I create a Card acc the server crashes. I don't know what to do.
This is the Error:

Hi, I've very little time to no time recently so I can't fix this problem now. Although, it seems like a simple fix with a PR done by someone, so once I find some time I will look into it and hopefully release a fix.

Fixed by #3
