Can not run complex report with ReportClientDocument using POJO beans.

Question

Hi All,
Any help would be very appreciated I have been stack on this issue for the last 4 hours.
My report has parameters, a ResultSet and subreports that themselves have both parameters and ResultSet.
The report runs well in Crystal Report Designer but not on my application with ReportClientDocument API.
The excpeiton I am getting is:

Hello,
If I understand correctly, you create a local report which choose report from Report Server. You have two query parameters in the report which are returned by stored procedure. Currently, you cannot get default values for these parameters when run the report.
Based on my test, if we haven’t configure these parameter with Available Values, we can reproduce the same issue. Also, caching issue may cause the same issue. If the issue is persist, please delete the corresponding report in the report server. Then, redeploy
it to check.
There is a similar issue, you can refer to it.
