Duplicated execution arise only in production environement

Dear Wix Community,

I am currently developing some metrics functions for my website to track views on my product dynamic pages with the following code:

$w.onReady(async function () {
    currentProduct = await $w('#dynamicDataset').getCurrentItem()

    getMetricsObject().then((results) => {

export function getMetricsObject() {
    return wixData.query('ProductMetrics')
        .eq('itemId', currentProduct._id)
        .then((results) => {
            return results._items[0]

export function incrementPageViews(currentViewsObject) {
    wixData.update('ProductMetrics', currentViewsObject)

This code works fine in the sandbox environment, with each page load incrementing views by 1. However, when deployed into the production environment, it increments page views by 2 instead.

I tracked the outputs of the functions, and here’s what they look like:

 currentView = 0
 // In sandbox environment
 oldView = 0
 newView = 1
 // In production environment
 oldView = 1
 newView = 2

I think this might be related to the asynchronous nature of my functions, but I can’t seem to pinpoint where the bug lies. Do you have any suggestions on how I should fix it? It would be much appreciated!
