GenerateYearlyReport_Performer Error

Here I get the error message on running the project, “Invoke System1_CreateYearlyReport workflow: The given key was not present in the dictionary.”

after opening the download monthly report page, the application closes and going for process transaction number 2, again same happens and so on.

@student

Could you please check once the value you provided in Config Excel file and the one in the process are same or not ?

It should be case sensitive and also it should be exactly same and there is no extra spaces and all.
