I have the same issue in a new App Workspace (Preview). Any updates?
My update: the problem persists.
My problem was resolved a few weeks ago. Just tried to copy a dashboard again and it seems to be working.

The problem still persists on my end
Necro'ing this thread. I'm experiencing the exact issue mentioned in this discussion. Did anyone come up with a solution or probable cause?
The problem is still there as of today 2/13/2019.
The only difference is that you get a confirmation message telling you the copy succeeded.
It does, in the sense you get a new "copy" of the dashboard.
But it is EMPTY.
Darn, that's disappointing to hear. Sounds like the issue has changed slightly for you. I'm still getting the couldn't be duplicated message.
