APIResponseError: body failed validation: body.parent.page_id should be defined

[cemonliu]

when i try to create a page with child block. It feedback the error with page_id should be defined.
I have specified the database_id when created page, if i remove the children parameter , it works fine.
notion.pages.create(parent={"database_id": database_id}, properties=new_page,children=new_child)

Sounds like the database_id you're giving isn't actually the id of a database but a page or something else? If not, I'd bet the error isn't really explicit and is triggered by something else on Notion's side. For example, I found this in their documentation, did you check it as well?

If the parent is a database, the property values of the new page in the properties parameter must conform to the parent database's property schema.

Today, I double confirm the issue again. I found the problem caused by wrong format in the data (children portion ) I need post. it's solved. Thanks guys.

For me it was the lack of a "properties" section, adding it solved

To help others (who may run into this)...

As @cemonliu points out, the error can be confusing. I ran into this while trying to create a page with no children. Turns out that children must be an empty list and not None. There may be similar validation errors on the API being reported incorrectly while they are in beta.

i was expected to see update in my pages

>body.properties.Name.name should be defined, instead was `undefined`.

body.properties.Name.start should be defined, instead was `undefined`.
>this is the error im getting
can you check this

For people trying to create a page under another page (and not under a database), the following has worked for me:

  notion.pages.create(
    parent={"page_id": page_id},
    properties={
        "title": [{"text": {"content": "my awesome title"}}],
    },
    children=[],
  )

Adding more properties like the ones in the Create a page API documentation raises errors such as:

APIResponseError: body failed validation. Fix one: body.parent.database_id should be defined, instead was `undefined`. body.properties.Name should be not present, instead was `{"title":[{"text":{"content":"some title"}}]}`.

For those who had the same problem in Apps Script, I had nested the title too much, commenting out one worked:

 'properties': {
          //'Title': {
            'title': [
              {
                'text': {
                  'content': 'PAGE_TITLE'
                }
              }
            ]
          //}
        }
