TTK Requests to PUT /parties/{Type}/{ID} endpoint fail

[theobadha]

Summary: A request to the PUT /parties​/{Type}​/{ID}​/ endpoint does not require an Accept header (as per the swagger documentation) However, building a request and leaving out the Accept header value, the test fails with an error message that says the Accept header is missing and required. Response:

{
  "status": 400,
  "statusText": "Bad Request",
  "body": {
    "errorInformation": {
      "errorCode": "3102",
      "errorDescription": "Missing mandatory element - Accept is required"
    }
  },
  "headers": {
    "content-type": "application/json; charset=utf-8",
    "cache-control": "no-cache",
    "content-length": "109",
    "date": "Tue, 05 Aug 2025 14:58:36 GMT",
    "connection": "keep-alive",
    "keep-alive": "timeout=5"
  }
}

Severity: Low

Priority: Low

Expected Behavior Requests should behave matching the api swagger definition. This request without the accept header should pass successfully with a Status code: 200
