Hi Dimitri Bologna,
Could you please the English version of the error to help me understand the meaning.
Also, press F12 in your browser to open Developer tools and check browser logs for any issue.
Also, have you updated the Google Map widget extension to include the Google map API key and then imported in ThingWorx? Please refer to following article for details: https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS188314&lang=en_US
