Error uploading data using Import CSV to Database Smart Service

A Score Level 2

We are using Appian 18.1 to bulk upload csv data to a sql server database. We are achieving it by using ‘Import CSV to Database’ smart service, exceltools plugin version 2.0.2(recently upgraded) to import the data to the database.

One of the csv file has 6 columns and around 30k records. There is no data transformations.

 

After around ~5 mins of upload, it throws with an exception on the Appian Interface with below error(data is though inserted in the database after some time):

"403 Access Denied: you dont have permission to view this page"

Did anyone faced same issue and possible workaround?
