Wix Paid Plan Backend: I'm trying to create a database entry onPlanPurchased() but nothing happens.

SOLVED: I made a mistake and used the wrong file extension .jsw instead of .js
The code works perfectly and is tested if someone needs this.

Hi there,

I created a new file, events.jsw, in the Wix backend and stitched together some code in order to create a new database entry in case someone purchases a plan. I tried it with a new account but there was no database entry and I am having a hard time debugging the code because I don’t know where to read the console for the backend code? Then I could add console.log() statements and probably debug it myself.

This is the code from events.jsw.

import wixData from 'wix-data';

export function wixPaidPlans_onPlanPurchased(event) { // If an purchase event is fired
    wixData.query("planEvents") // query the existing database and search for the userID
        .eq("userID", event.order.userID) 
        .find()
        .then( (results) => {
 if(results.items.length > 0) { // if there is a database object with the userID inside
 let databaseRowID = results.items[0]._id; // then get the database ID of the object
 let updatedMaxUserLevel = results.items[0].maxUserLevel + event.order.validFor.period.amount; 
 let toUpdate = { // create a new object with the new data from the event
 "_id":                  databaseRowID,
 "userID":               event.order.memberId,
 "maxUserLevel":         updatedMaxUserLevel,
 "currentPlanValidFrom": event.order.validFrom,
 "currentPlanValidFor":  event.order.validFor.period.amount,
 "currentPlanObject":    event 
                  }; 
                updateDatabase(toUpdate) // update the current object with the new data

            } else { // handle case where no matching items found.                                                                                           
 let orderData = { // create a new database object from the event.data                                                                              
 "userID":               event.order.memberId,
 "maxUserLevel" :        event.order.validFor.period.amount,
 "currentPlanValidFrom": event.order.validFrom,
 "currentPlanValidFor":  event.order.validFor.period.amount,
 "currentPlanObject":    event
                 };
                insertDatabase(orderData) // create a new database entry
            }
    })
}   

function updateDatabase(object) {
    wixData.update("planEvents", object)
    .then ( (results) => {
 let item = results;
    })
    .catch( (err) => {
 let errorMsg = err;
    });
}

function insertDatabase(object) {
    wixData.insert("planEvents", object)
    .then ( (results) => {
 let item = results;
        })
    .catch ( (err) => {
 let errorMsg = err;
    }); 
}

I also have a database with the following structure:

Any help is appreciated. Thanks!
