Edit Print Design Document Blank Page

[ghulamostafa]

I have installed print_designer 1.4.3 on ERPNext. When I try to edit any print format using the print_designer, it shows blank page. The console shows the following error:

Could it be related to cache? I have run the bench --site all migrate command. I have restarted all of the containers as well. I have tried to clear the browser cache history also.

Also this is in the console with 404 with the URL https://mysite.dev/assets/print_designer/dist/js/print_designer.bundle.HOZH2B33.js
