Sign Up (Cloud functions field validation)

Technical Issue Reporting
#1

Hey guys,
So I’m trying to make some special validations on sign up with Cloud Functions but my code doesn’t seem to work and I’m not sure why because I followed the docs.

const validateSignUp = (request) => {
  // Validate username
  if (!(/^[a-zA-Z0-9.\-_]*$/.test(request.username))) {
    throw "Invalid Username";
  } else if (request.username.length < 2) {
    throw "Invalid Username";
  } else if (request.username.length > 32) {
    throw "Invalid Username";
  }

  // Validate password
  if (request.password.length < 4) {
    throw "Invalid Password.";
  }
}

Moralis.Cloud.beforeSave(Moralis.User, () => {
  // any additional beforeSave logic here
}, validateSignUp);

This is how I was able to call a validation function:

const validateSignUp = (request) => {

  logger.info("before printing username in validateSignUp");
  logger.info(request.object.get("username"));
  logger.info("after printing username in validateSignUp");
  

  if (!(/^[a-zA-Z0-9.\-_]*$/.test(request.username))) {
    throw "Invalid Username";
  } else if (request.username.length < 2) {
    throw "Invalid Username";
  } else if (request.username.length > 32) {
    throw "Invalid Username";
  }

  // Validate password
  if (request.password.length < 4) {
    throw "Invalid Password.";
  }
}

Moralis.Cloud.beforeSave(Moralis.User, (request) => {
  logger.info("in before Save");
  logger.info("before printing request in beforeSave");
  logger.info(JSON.stringify(request));
  logger.info("after printing request in beforeSave");

  logger.info("before printing username in beforeSave");
  logger.info(request.object.get("username"));
  logger.info("after printing username in beforeSave");
  validateSignUp(request);
});

Thanks that works, but I guess the docs are wrong then?

Also where can I check those logs printed by logger.info?

You can check the logs in server dashboard in logs -> info

I wasn’t able to run that syntax either. :thinking: Will have to enquire regarding this.

When i use this code i get “TypeError: Cannot read properties of undefined (reading ‘length’)” when i use .lenght in condition.

#7

that usually means that the variable before .length is undefined

you could update the code to check if the user has a password

#8

Seems like i have it all … can’t figure it out
