Rest API for Pick Wave Release (Auto Pick Confirm and Auto Ship Confirm)

Summary:

We have a need to run Pick through API. I created a pick release rule with auto pick confirm and ship confirm. I ran a test from Oracle Fusion and it went through fine. Trying to run pick release through API. I have the following payload. When we execute the Payload, I get the response 'S', but the order line still remains as "Pick Released". The Pick Release rule is that with Auto Pick Confirm and Ship Confirm. Any help or suggestion is greatly appreciated.
