While using OOTB "Dashboard metrics" template, keep getting "The selected page 'ABC' expects an object of type 'Y', which is not available here."

Hi,

While using the OOTB  "Dashboard metrics" template, I keep getting this error:

• "The selected page 'ABC' expects an object of type 'Y', which is not available here."

My questions are:

• Why would a dashboard be passed an object at all?
• I get the same error using a microflow which retrieves object  Y from an association with X from the calling page.
• I get the same error using the Report Chart widget.

While I understand the premise of the error message, how do I resolve this without starting from an overview page with a list view, since these widgets actually handle lists of objects to graph? What am I missing?

Any hints are appreciated,
