I've installed an AppExchange package: Salesforce Communities Management (for Communities with Chatter) - AppExhange Package Link - The application Provider is "Salesforce".
In this package there is a particular report named as: CH T - Knowledgeable People Per Topic
When I try to read this report using following APEX code:
Reports.ReportDescribeResult descRes = Reports.ReportManager.describeReport(r.Id);
I get a "Salesforce System Error", and this System error is not being trapped by any try/catch container. There is no issue if I try to read any other report.
Salesforce System Error: 1621110285-498685 (-1627279259) (-1627279259) An unexpected error has occurred. Your solution provider has been notified. (reports)
I'm unable to trap the error and this is breaking the full code. Can someone point me to understand why only this particular report cause trouble in Reading it?
