Valid Notion page IDs are rejected

[nihaals]

Bug Description

Notion documents page IDs as being UUIDv4, however I have some page IDs that don’t have a 4 in the correct position. This means some Notion nodes reject the input even though the ID came directly from a Notion API response.

n8n’s regexes that neither the ID or the URL from the API response match:

	},

To Reproduce

1. Keep creating Notion pages until/find an existing page that doesn’t have a 4 in the expected position
2. Pass it into a page action node, for example archive page as an ID
3. Notice you get an error: “Page parameter's value is invalid. This is likely because the URL entered is incorrect [item 0]”

Expected behavior

The page is archived.

Hey @nihaals,

We have created an internal ticket to look into this which we will be tracking as "GHC-235"

Hey @nihaals,

Can you share some URLs that show the errors? Notion page urls should be UUID 4 looking at their documentation.

I think this might have changed within the past couple of weeks as the first page I just made wasn't a UUIDv4: https://www.notion.so/10336a9a827580b895e3f7ff1d3ea585 (the page is public).
