Hi @charith_wickramasing,

Use below Syntax and check it once


Hi @charith_wickramasing,

Please find the revised workflow.
It will work perfectly fine, all you need to update is to provide the same header as in webpage :

  1. row(“Actions”).ToString
  2. row(“WIID”).ToString

Seems the error is because your foreach element is empty. Please check your filtered list count and see if it has any rows.
