How to resolve the file not exported problem while exporting from JavaScript ReportViewer?

Syncfusion Web ReportViewer supports exporting the rendered report into various formats like EXCEL, WORD, PDF, CSV, PPT, and HTML. The exported file will generate zero bytes or PostReportAction will not return resultant data if dependent assemblies of ReportViewer are not published with proper format in IIS hosted environment. To resolve this, ensure that the build version and framework version of the assemblies are unique.

List of ReportViewer dependent assemblies are,

• Syncfusion.Linq.Base
• Syncfusion.Compression.Base
