Export API call returns only module headers
I am trying to export out data from a module via an API call using an existing export action. Have successfully initiated the export action and retrieved the file details (chunk numbers etc), however when I attempt to download the first (and only) chunk details the API call only returns the module headers without any of the data.
Attached is screenshot from postman showing the response.
I can confirm that the file created / downloaded when running the export action manually from Anaplan does result in a file with data.
Any help will be appreciated.
