Value must be null when using the exists/notExists operators

Hello,

I am using post_analytics_conversations_details_query with the body below.

body = {
  "interval": "2022-07-31T23:00:00.000Z/2022-08-30T23:00:00.000Z",
  "order": "asc",
  "orderBy": "conversationStart",
  "paging": {
    "pageSize": "100",
    "pageNumber": "1"
  },
  "conversationFilters": [
    {
      "type": "or",
      "predicates": [
        {
          "type": "dimension",
          "dimension": "conversationEnd",
          "operator": "notExists",
          "value": null
        }
      ]
    }
  ]
}

I am receiving the following error message below

value must be null when using the exists/notExists operators

In the past when I had this problem using another endpoint, I basically got around it by changing null to False and it worked, however, that is not the case this time.

Is there something else that I can do to use this endpoint via the Python SDK?

Thank you very much!

Chris

I changed it to "value": None and it worked.
