Hi. I would like to automatically add a block to a WorkDoc that includes indentation. If I query an indented WorkDoc I get the following:

          {

            "id": "obfuscated",

            "type": "bulleted list",

            "content": "{\\"alignment\\":\\"left\\",\\"direction\\":\\"ltr\\",\\"deltaFormat\\":[{\\"insert\\":\\"Hello3\\"}],\\"indentation\\":2}"

          }

If I mirror the content back using the following GraphQL:

mutation ($doc_id: ID!, $content: JSON!) {

  create_doc_block(type: bulleted_list, doc_id: $doc_id, content: $content) {

    id

  }

}

{

  "content": "{\\"alignment\\":\\"left\\",\\"direction\\":\\"ltr\\",\\"deltaFormat\\":[{\\"insert\\":\\"Hello3\\"}],\\"indentation\\":2}",

  "doc_id": 12345

}

I get the following error:

  "error_data": [

    {

      "error_type": "Unrecognized property",

      "error_msg": "unrecognized property [indentation] in content"

    }

  ],

Why is it that indentation is fine for reading but not for writing. I did look at the Quill playground which seems to suggest I can add an indent value to the attributes object but that seems to get ignored by the API. So… is this possible at all?
