Web tracca does not load, it stays in the blue circle and at the end it opens co

I'm sorry for my English
First of all thank you very much.

My problem is that my web page does not load, it appears circling the circle and at the end a message says "connection failure" and I check the browser console and I get this error message "Uncaught TypeError: Can not read property 'mapCarto' Of undefined at app.min.js: 23 "

I need help, please.

Thank you
