@dosubot[bot] commented on GitHub (Mar 20, 2025):

The Array[Object] should be usable in the HTTP block for sending an image array to the server. The files parameter in the request body is defined as an optional array[object], which can include image URLs. Each object in the array should have a type (e.g., image), a transfer_method (e.g., remote_url), and a url (e.g., "xxx.png"). Ensure that each object in the array is correctly structured as per the API documentation:

{
  "files": [
    {
      "type": "image",
      "transfer_method": "remote_url",
      "url": "xxx.png"
    }
  ]
}

If you are encountering issues, it might be due to incorrect formatting or missing required fields in the objects within the array. Additionally, ensure that the list does not exceed the maximum allowed length and that each element is a dictionary (object) [1][2].

Files in the workflow are not like other types. So you can not use it like this.
