Payload input in FOR loop getting rearranged

Summary:

I am creating a workflow agent to create multiple transfer orders based on Excel file input. The file is being read successfully and the Payload in generated as expected.

But when the JSON array is passed in the FOR loop, the payload columns are getting rearranged, and the transfer order creation fails.
