Unable to create datasource for excel file in datagateway

Dear Support Team,

I have one power bi report where i have used data gateway to connect sql server and refresh the report, It is working fine.

Now for one of the report i used excel file as datasource and to refresh that datasource i am creating excel datasource in data gateway where i have provided the data source name then the sharepoint path of the excel file then selected windows and provided the user credentials which is used to connect the sharepoint. But when click on create button it is throwing below error:
