I am trying to call an Action which has a required header parameter. Thought the Action command might fix this (instead of Post), but I get an error when running the script:
API Doc:

My Script:
ApplyJson Into getResult1
{}
Action PartConfigurationRevisionHandling.svc/ConfigPartSpecRevSet(PartNo={#input.PartNo},SpecRevisionNo=1)/IfsApp.PartConfigurationRevisionHandling.ConfigPartSpecRev_Release Using getResult1 Into actionResult1
{}
Resulting error:
2025-02-07 08:21:26 Application exception error: {"error":{"code":"ODP_MISSING_PRECONDITION","message":"A precondition is missing in the request."}} POST PartConfigurationRevisionHandling.svc/ConfigPartSpecRevSet(PartNo='TEST1',SpecRevisionNo=1)/IfsApp.PartConfigurationRevisionHandling.ConfigPartSpecRev_Release failed with 428
Any ideas on how to fix this? I can get it to work in Postman by adding the required Header Parameter. But in SAR there is only one Header Parameter available.
