Plugin is not working

Hello!

I tested your plugin a lot on a local copy of the site, but now that I have installed the plugin in the production environment, it is not working.

Coupon status does not load, look: https://prnt.sc/118dwm4

I noticed that some errors appear on the console, would it be related?

Could you help me identify what is going on?

Console Errors:
