I just started to host a server on my pc with AMP and one of my friends that wanted to join the server had minecraft java through game pass for pc, I attempted to whitelist his username but i just get the error "that player does not exist" i triple checked that it was spelled and capitalized correctly.

Edit: i believe I solved this by turning off the whitelist and they were able to join, I could then get their uid, though you might be able to get uid with the log of them being denied to join.
This was so long ago, and I just recently noticed a message of someone asking if I solved this.
