Error when creating the report engine

[#1]

Good time of day

I want to get information about the report's data providers using the sdk.

To do this, I create the report engine object.

Error appears

com.businessobjects.rebean.wi.CommunicationException: Unable to instantiate ReportEngine.

why the report engine object may not be created?

I want to get the data providers and then the request text. I get similar information through the rest api, but the request text is returned without formatting. It is possible that the sdk will preserve the formatting as it is in the interface.

// Initialize Webi report engine
ReportEngines reportEngines = (ReportEngines) enterpriseSession.getService("ReportEngines");
ReportEngineType type = ReportEngines.ReportEngineType.WI_REPORT_ENGINE;
ReportEngine reportEngine = (ReportEngine) reportEngines.getService(type);
