Here is my code:

// MAIN.JS
Parse.Cloud.define('findUserWithUsername', function(request, response) {
  console.log('MAIN => findUserWithUsername');
  user.findUserWithUsername(request.params.username, response.success, response.error);
});

// USER.JS
exports.findUserWithUsername = function(username, success, failure) {
  console.log('findUserWithUsername - username: ' + username);
  Parse.Cloud.useMasterKey();

  var query = new Parse.Query(Parse.User);
  console.log('findUserWithUsername - query created')
  query.equalTo("username", username).first().then(function(_user) {
    if (typeof _user !== 'undefined') {
      console.log('findUserWithUsername success -> ' + _user);
      success(_user);
    } else {
      console.log('findUserWithUsername success -> no user found');
      success(null);
    }
  }, function(_error) {
    console.log('findUserWithUsername - error: ' + _error);
    failure(_error);
  });
}

// USER.TEST.JS
function deletePreviousUser(username) {
  console.log('deletePreviousUser');
  return Parse.Cloud.run("findUserWithUsername", {username: username}).then(function(user) {
    console.log('findUserWithUsername succeed');
    return (user == undefined) ? Parse.Promise.as() : Parse.Cloud.run("deleteUser", {userId: user.id});
  }).then(function(result) {
    return Parse.Promise.as();
  }, function(_error) {
    return Parse.Promise.error(_error);
  });
}

I never had such a error message with Parse.com and I've no idea of what does it mean. Any suggestion?

Answer 1

I had the same issue, it solved by restart the Parse Local Server.

Answer 2

I experienced the same error.
This error had started to occur suddenly without modifing codes.
In my case, changing code from "response.success();" to ""response.success("");" fixed the problem.

Please try to change the line "success(null);" to "success("");"
