Hey folks! I am trying to make a full verification process over the api. After the flow initialisation I am making a post request to

{{baseUrl}}/self-service/verification?flow=[flowId]

with the json data in my request... But when the request is successfull I always get html as response and not the data which is stated out in the api docs - https://www.ory.sh/docs/reference/api#tag/frontend/operation/updateVerificationFlow

{
  "active": "string",
  "expires_at": "2019-08-24T14:15:22Z",
  "id": "497f6eca-6276-4993-bfeb-53cbbbba6f08",
  "issued_at": "2019-08-24T14:15:22Z",
  "request_url": "string",
  "return_to": "string",
  "state": "choose_method",
  "type": "string",
  "ui": {
    "action": "string",
    "messages": [
      {
        "context": {},
        "id": 0,
        "text": "string",
        "type": "info"
      }
    ],
    "method": "string",
    "nodes": [
      {
        "attributes": {
          "autocomplete": "email",
          "disabled": true,
          "label": {
            "context": {},
            "id": 0,
            "text": "string",
            "type": "info"
          },
          "name": "string",
          "node_type": "string",
          "onclick": "string",
          "pattern": "string",
          "required": true,
          "type": "text",
          "value": null
        },
        "group": "default",
        "messages": [
          {
            "context": {},
            "id": 0,
            "text": "string",
            "type": "info"
          }
        ],
        "meta": {
          "label": {
            "context": {},
            "id": 0,
            "text": "string",
            "type": "info"
          }
        },
        "type": "text"
      }
    ]
  }
}

Am I missing anything to receive this data?
