Hello, Umbraco comunity. Is there any ideas of how can I get Block list content with Graphql ? It does works fine for all other elements, but not for the Block List.

Example of query:

query($id: ID!) {
  blockList(id: $id, preview: true) {
    ... on BlockList {
      mainPageBlockList {
        ... on BlockListItem {
          content {
            contentTypeAlias 
          }
        }
      }
    }
  }
}

Result is

{
  "data": {
    "blockList": {
      "mainPageBlockList": null
    }
  }
}

Not sure why I'm getting null here when it works correct for other content.
