Error when saving product

[Alessandro]

Hello,

I'm having this issue when saving a product in my shop stage.altomilano.it.

When i click save, the backend starts the saving process, but it only works partially. For example, simple infos like title and description do get saved. But at some point, the process ends up in a 500 error as showed in the screenshot, and things like categories do not get saved. 

The file that goes in error is the following: adminXXXXXXXXX/themes/new-theme/public/main.bundle.js, i also attached it below. The line indicated is 253 (for fast serch, look for "!function(e,t){function i(e,t)"), but i don't think i can understand the error.

Could you please help me? Thanks.

 

EDIT: i tried disabling al non native modules and all overrides, and deleting cache, but it still did not work.

main.bundle.js

Activate the debug mode and check the details of the 500 error (click on the profile or in browser console) - the Javascript is only the trigger, there is something else on Server side causing it.
