@SethFalco - you'd recently worked on the this service, so curious if you have any ideas? I'm not sure how this would be happening from a cursory glance at the code and the API response under various conditions. Wondering if it could be something encoded related with the username (e.g. a username containing a space or some other escaped character)

Just gave this a peek, but without knowing the input I'm a bit confused how this occurred, to be honest.
Spaces aren't allowed in a freeCodeCamp username either, so that shouldn't be it I don't think. (at least not directly)

const isValidUsername = str => {
  if (!validCharsRE.test(str)) return invalidCharError;
  if (str.length < 3) return usernameTooShort;
  if (isHttpStatusCode(str)) return usernameIsHttpStatusCode;
  if (!isUsernameLowercase(str)) return usernameUpperCase;
  return validationSuccess;
};

• Basically, it can only have characters a-z, A-Z, 0-9, -, _, and +.
• Must be at least 2 characters.
• Can't be an HTTP status code?
• Can't have uppercase characters.

Based on this the issue is most likely the + symbol that can be used in usernames. I've just reproduced the internal server error as well. I'll tackle this soon!
