Problem copying page

Hello

The problem occurs with RS8.1.8/8.2.3 with laravel/bootstrap, but also occurs in other frameworks.

Copy the “View Page” to “View Page2”.

Then, I get the following error:

Before making the copy it worked fine.
What could be the problem?

Thanks

The master details configuration you made on the page is the issue. Remove it and duplicate the page, then configure it for the view page and see if it occurs. Or you can just remove the configuration for the duplicate view page.
