Page Include Fails

I have been using page include for years.

If I put the Id in the page include “MemberId=a0gj00000010mVUAAY” it does not find the record.

If I assign a single specific record Member as a0gj00000010mVUAAY. Then previewing just the included page on it own finds the record

You might have better luck with {{$Model.Member_Selected.data.0.Id}}
