Parameter prompt is coming after migrating to 13.0.2

Hi Team,

Getting weird issue. After migrating the CR from 10.0.3 to 13.0.2 it prompts for parameter though we are assigning them in code. If we give the parameters in prompt window it gave connection failed error.

in older version i.e. 10.0.3 it never prompts for parameters just display the report.

One Blog was suggesting to migrate to 13.0.9 version. I uninstalled 13.0.2 developer version and installed 13.0.8 but in GAC CR dlls are of version 13.0.2 not of 13.0.8, not sure if that should be the case.

Appreciate any help on this.

Thanks,-Manish
