Delphi EMS FireDAC: Unable to Open Dataset [FDMemTable]

I work with a simple client server application using EMS (for example, for a future iOS application) in Delphi.

This question is a continuation of my previous question with a different error.

This is my previous question with another problem from which I followed Marco's suggestion.

Problem: Now I have an error when I pass the parameter from client to server.

Project EMS_Test_Client_Project.exe raised exception class EFDException with message '[FireDAC][Comp][DS]-206. Cannot open dataset [FDMemTable]. A DataTable or a DataView must be supplied. Hint: if that is TFDMemTable, use CreateDataSet or CloneCursor to open dataset'.

Thus, I have the Image1 property of the TFDMemTable properties (DatSTableName: QRowParam) with the Param parameter, which causes an error.

Problem TFDMemTable

I have Image2 TFDMemTable properties (DatSTableName: QRows) without a Param parameter that works.

Working TFDMemTable
