Issue/Introduction

We discovered that the JSON body posted by the Integration REST agent (v24.0.1) is transmitted incompletely to the remote API when the content is empty.
This leads to unpleasant impacts.

By sending a POST request to https://httpbin.org/ the customer discovered that IG_REST changes the payload:

DEFINED:

{
  "feed": {
    "feed": "CURVES",
    "subfeed": "TPF_CURVE",
    "cob_date": "2025-05-22",
    "params": {} <--- empty
  },
  "message_args": {
    "priority": 50,
    "max_retries": 1,
    "retry_delay": 30
  }
}

SAVED to Report:

{
  "feed" : {
    "feed" : "CURVES",
    "subfeed" : "TPF_CURVE",
    "cob_date" : "2025-05-22",
    "params" : { } <--- notice the additional whitespace between the brackets
  },
  "message_args" : {
    "priority" : 50,
    "max_retries" : 1,
    "retry_delay" : 30
  }
}

RECEIVED by the HTTP server:

{
  "feed": {
    "feed": "CURVES",
    "subfeed": "TPF_CURVE",
    "cob_date": "2025-05-22",
    "params": ,  <-- notice the value '{}', CR ('\n') and closing bracket '}' disappeared
  "message_args": {
    "priority": 50,
    "max_retries": 1,
    "retry_delay": 30
  }
}
