Cloud Function .save() returns undefined

[nigel]

This successfully saves to the database.

return polkamonFirst.save();

But the returned value is always undefined in Moralis logs.

How can the saved object be returned?

Moralis.Cloud.define("saveDamage", function(request) {
    const query = new Moralis.Query("Polkamon");

    query.equalTo("polkamonId", request.params.polkamonId);
  
  	if (request.params.damage <= 0) {
    	return "damage needs to be greater than 0"; 
    }

    query.first()
    .then(function(polkamonFirst) {
        var newHp = polkamonFirst.get("hp") - request.params.damage;

        polkamonFirst.set("hp", newHp);

        return polkamonFirst.save();
    });
});

the .save() functions is async, so you might need to add an await on it.

Thank you for your help.

Yes the fix required using await instead of then() for async. I also updated the Cloud Function to be async.

Here is my working Cloud Function that returns the saved object.

Moralis.Cloud.define("saveDamage", async (request) => {
    const query = new Moralis.Query("Polkamon");

    query.equalTo("polkamonId", request.params.polkamonId);
  
  	if (request.params.damage <= 0) {
    	return "damage needs to be greater than 0"; 
    }
  
  	const polkamonFirst = await query.first();
  	
    var newHp = polkamonFirst.get("hp") - request.params.damage;

    polkamonFirst.set("hp", newHp);

    const polkamonSave = await polkamonFirst.save();
	return polkamonSave;

});
