test@test,com as opposed to [email protected]var result = await _userManager.CreateAsync(user, registerRequestDTO.Password); and it throws this error "Username 'test1@test,com' is invalid, can only contain letters or digits." and I can't seem to figure out how to make it handle this error correctly so that it is in the format below, I don't think I can just hard code it because what if a different error is thrown, i want it to always come back in the format, Key: ['array of errors', '...' ] like below.
