I have a SharePoint Subsite SS.1 which inherits a Lookup Site Column "Col1" from its parent site S.0.
I have a Power automate flow on a list List1 in the subsite.
If I make Col1 a mandatory field in List1, I am seeing an error in the workflow, "The required field "Col1" data type is not supported clientRequestId: <CRI> serviceRequestId: <SRI>"
It does not give the error if Col1 is made optional, or if Col1 is redefined as a Local site column in SS.1.
So I have a workaround (I made Col1 Optional in List1 temporarily), but this does not serve the Business purpose: I need Col1 to be mandatory
ADDITIONALLY, The Column Col1 is not appearing as a dynamic variable in the flow, irrespective of whether it is optional or Mandatory
