Map doesn't show (js error Uncaught ReferenceError: google is not defined)

Hello,
I have problems to view a map on my local wordpress website (the online version works fine ..).
When I copy the html generated page of my distant website on my local storage, it works to.

The 2 files where the error is generated (wp-google-map-pro/js/core.js) are strictly identical.
On the local version, the core.js file is called after all the google maps api js files.

I am out of ideas to solve this problem and hope that someone can help me.
Thank you.
