Copy Link function - Not working correctly

Hi,
We have a customer using the new web client but we noticed that the copy link function does not work, if I modify the link manually then it works.

Example
Copy Link function link
https://docs.example.com/link/AAAA1111-BBBB-2222-CCCC-3333DDDD4444/show?object=ZZZZ9999-YYYY-8888-XXXX-7777WWWW6666

When trying to open the link I get "The page cannot be displayed because an internal server error has occurred."

However, if I manually modify it to include /vnext/ and an additional objid parameter, it works correctly
https://docs.example.com/vnext/link/AAAA1111-BBBB-2222-CCCC-3333DDDD4444/show?object=ZZZZ9999-YYYY-8888-XXXX-7777WWWW6666&objid=0-123

So it seems that the generated link is missing some required parts or something is misconfigured.
Any ideas? 

Thanks.
