Scheduling a report that has default parameter values throws BAD Request error

[kothany]

I have a report with some required parameters(paramA="default_a", paramB="default_b") with default values, it works as expected when I run it from jasper server UI or by using jasper rest client (https://github.com/Jaspersoft/jrs-rest-java-client). While scheduling this report I am supplying the parameters (paramA="2012", paramB="xyz") using the rest client  like below :

    Job job = new Job();

        JobSource s = new JobSource();
        Map<String, Object> reportParamsMap = new HashMap<String, Object>();     
        reportParamsMap.put("paramA", "2012");
        reportParamsMap.put("paramB", "xyz");
        s.setParameters(reportParamsMap); 
        job.setSource(s);

..... set other job fileds (label, description, outputforamts etc ).  

OperationResult<Job> result = session.jobsService().scheduleReport(job);

and my json that was sent  to http://localhost:8080/jasperserver/rest_v2/jobs is 

{  
   "id":null,
   "version":null,
   "username":null,
   "label":"MyReport",
   "description":"Scheduling my report to run daily",
   "creationDate":null,
   "baseOutputFilename":"MyReport_UserID_1546020148418",

      "usingDefaultReportOutputFolderURI":null,
      "outputLocalFolder":"/reports/Test",
      "outputFTPInfo":null
   },
   "source":{  
      "reportUnitURI":"/reports/Test/MyReport",
      "parameters":{  
         "parameterValues":{  
            "paramA":"2012",
            "paramB":"xyz"        
         }
      }
   },
   "outputFormats":{  
      "outputFormat":[  
         "PDF"
      ]
   },
   "trigger":{  
      "simpleTrigger":{  
         "id":null,
         "version":null,
         "timezone":null,
         "calendarName":null,
         "startType":2,
         "startDate":"2018-12-28 12:02",
         "endDate":null,
         "misfireInstruction":null,
         "occurrenceCount":1,
         "recurrenceInterval":0,
         "recurrenceIntervalUnit":"DAY"
      }
   },
   "outputTimeZone":null
}

And I get :

....

When I do not set the parameters to the job source like (  s.setParameters(reportParamsMap); ), the scheduler creates the job but with the default parameters which is pointless in my case.

Question: How to send report parameters dynamically while scheduling a job. 

UPDATE-1: Jasper server versin 7.1.0. produced above errors 

UPDATE-2: Jasper server versin 6.4.0 does not  produce the above error but it schedules the report with default parameters.

Ok.It was my mistake while creating the report parameter map. So by changing the follwing code from :

 reportParamsMap.put("paramA", "2012");

 reportParamsMap.put("paramB", "xyz");

to 

 reportParamsMap.put("paramA", new String[]{"2012"});

 reportParamsMap.put("paramB", new String[]{"xyz"}); // you can set list of strings too

resolved my problem.
