Hi, I am trying to create cases via DX APIs v2 using below JSON,

{    "caseTypeID":"XX-YYYY-Work-Dispute",    "content":{       "pyLabel":"Loan",       "pyDescription":"Dispute request case"    } }

but it seems to be failing with below error

{
  "errorClassification": "Invalid inputs",
  "localizedValue": "One or more inputs are invalid",
  "errorDetails": [
    {
      "message": "Error_Invalid_Inputs_content",
      "erroneousInputOutputFieldInPage": "",
      "erroneousInputOutputIdentifier": "",
      "errorClassification": "",
      "localizedValue": "Invalid request data",
      "messageParameters": []
    }
  ]
}

I have tried different json combination and verified the JSON is correct. But still it is returning this error. Am I missing something here??
