Datasnap param problem

[dlucic 1]

I have a problem with my DataSnap client application on Android 11 OS. Not every time but from time to time and on different places in my code. Sometimes I recive this message

 

 

When i click Break debuger points on this line in code

 

 

What can be a problem

Does it always fail on the same parameter?

I'd probably do it like this, but it depends on the declaration and description of the GetOptParameter method.

  var
    FNameOut: AnsiString;
  begin
    ...
    FNameOut := UTF8Encode(ParamName);
    if FDSBase.GetOptParameter(0, FieldNo, @FNameOut, ParamType,  ...

I made a simple test application as you tell me but I never get error as one in my application. New app has all the client data sets as my original application

 

 

When I click on button List param my test app fill Listbox with all params from the CDS selected by Radiobuttons. 

 

 

Then I select one of params and click on the other button Test param. This is onClick method code

 

 

I never get error as I get in my original application
