Hi ,

We're on Infinity 23.1.0, trying to build new case types using constellation. We're hosted on-prem and using Pega static CDN for the constellation app static. 

During this we're seeing some errors in the case type processing, errors observed in the case type submission.

Issue observed  is with DX API with Patch Method, where once the case is setup and trying to submit, it is failing with 400 status code and ifMatchHeader missing.

Anyone has seen this error? 

Error: “Required parameter ifMatchHeader has no value”  

Response: 400 http status code.

Resource: api/application/v2/ assignments/{assignmentID}/actions/{actionID}

Response Payload:
