Nested number/bullet list combination ends up with error

[KarolNov]

_{Discuss in #public-issue-15--nested-numberbullet-list-combination-ends-up-with-error}

I've a deeply nested list items in my .md file, like this:

1. **Something important**

    1. Sub step one
        - something to remember
        - parameters: 
          - param 1
          - param 2
          - param 3

This formats correctly in GH:

1. Something important

   1. Sub step one
      • something to remember
      • parameters:
        • param 1
        • param 2
        • param 3

but when converted to blocks and pushed as children element in the Notion API call I get error: '{"object":"error","status":400,"code":"validation_error","message":"body failed validation: body.children[1].numbered_list_item.children[0].numbered_list_item.children[0].numbered_list_item.children should be not present, instead was `[{\\"object\\":\\"block\\",\\"type\\":\\"bulleted_list_item\\",\\"bullete...`."}'. I tried recreating that styling manually in Notion and it seems to work.

Hi, thanks for submitting the issue. I've looked into this and I can reproduce the problem, but it seems it's a limitation imposed by Notion: the block structure is correct, but they allow only up to two levels of nesting in a single request when appending block children. Related docs: https://developers.notion.com/reference/patch-block-children

If that's the cause of your issue, then I assume you'd have to wait for the first request to be fulfilled, grab the resulting IDs, and then append the "deeply nested" children. It seems like the only alternative would be flattening the list, but that kind of defeats the purpose of having nested children...

What do you think @marissamarym?
