Hello,
We are working on deciding modernization approach of classic sites, and we thought of keeping pages into classic mode, while list and libraries into Modern mode.
Considering this approach, we have applied customized master page ( with custom java scripts in it) to classic page, however when we go to list and libraries in modern view, it's throwing following error, and we could realize that it's coming from the master page applied on the classic page.
My confusion is - If Modern UI has no concept of master page, then why classic master page is affecting a modern page of list and library?
Best Regards,
