Expensify Export Reports: "Mark as Exported" report feature not working

I am trying to create a daily export of Expensify reports and prevent duplicates. Once exported, I parse the report with CSV parser and then import to Airtable. The entire scenario is working as expected with the exception of the “Mark as Exported” setting for the exported Expensify reports.

This error causes the already exported reports to be exported again on the next run.

The ‘Export a Report’ module’s ‘Perform Action on Finish’ feature is not working.

Setup:

Module:Expensify - Export a Report
Action: I have ‘Perform Action on Finish’ set to true and the action set to ‘Mark as exported’ with the custom label AirtableSyncComplete.
Filter: I am using the ‘Marked as Exported’ filter with the same AirtableSyncComplete label to prevent duplicates.
My Expensify Role: I am a Domain Admin on my Expensify account.

The Problem: The action completes without any errors, but the reports are not being marked as exported in Expensify. I have confirmed this in two ways:

  1. When I run the scenario again, it exports the exact same reports (duplicates). The ‘Marked as Exported’ filter is having no effect.
  2. There is no comment or history on the reports in the Expensify UI to show that they were marked.

It seems the write-back ‘Mark as exported’ API call from the module is failing silently.
