New Document List '|0' does not exist at site with URL '|1'.
When trying to create a new document, from a custom content type (which has a template), starting from the Documents Webpart, Sharepoint opens the following link: https://tenant.sharepoint.com/si...
Found this URL that says the 'Documents' Library is missing and to create a new one or restore the old one.

Didn't work for me.
My situation is that we are converting our Classic Site Collection to a Modern experience. If I use a classic page with the web part to the Document Library it all works fine.
Solved it for me by switching the Default open behavior for browser-enabled documents: setting under Advanced Settings to use the Default which in this case is the Browser client.
Working now.
