"Map object not initialised." error on SSRS report

Hi ,

I am getting the below error in my controller class when I run my SSRS report.

"Map object not initialised. "

Running the report based on caller .

reportQuery = this.parmReportContract().parmQueryContracts().lookup(this.getFirstQueryContractKey()); // error occurring here

if(this.parmArgs().record() && this.parmArgs().dataset() == tableNum



inventSumRecord = this.parmArgs().record();


And I am not using the contract class as parameters are not required.

Please any suggestions on this.
