[Solved] An internal error has occurred. Please contact your system administrator. File export using sys operation framework

Hi Folks,

Recently I have been using SysOperatioonFramework to export data in excel. While running the code out of batch its working fine but as soon as I am calling this from Sysopertionframewrok, the system doesn't show anything on front end while debugging its giving error

An internal error has occurred. Please contact your system administrator.

Well, it's a minor mistake in the controller class. You need to define the execution mode for your service class (code in controller class)

this.executionMode = SysOperationExecutionMode::Synchronous

Save | Build | Run

It should work for you as well.
