Searching does not work

[nynevi]

Discovered while working on transitive-bullshit/nextjs-notion-starter-kit#618

The line here https://github.com/NotionX/react-notion-x/blob/master/packages/notion-client/src/notion-api.ts#L606
makes the below request:

curl --location 'https://www.notion.so/api/v3/search' \
--header 'Content-Type: application/json' \
--header 'Cookie: __cf_bm=l9fYQeZBInjE_IYkZfI39Rl84cClfIeJ9kCFQsKLGpc-1719470820-1.0.1.1-qFgBx5G_xqV_lkEMjjrVP5CSifPI.ZZ5vTvMbItNYy0tlItIWVr46e_2qYJYcXpmkS7OvvPlmWZCcr_ttBADkw; _cfuvid=T0dzvs1rxC8sFknZk47Efnx912M1XYiciVUPvyZ8S8A-1719470820038-0.0.1.1-604800000; device_id=6513a169-b1fc-404a-9ce8-3d4f6e450778; notion_browser_id=5d90bc05-2cad-4554-b6c5-f9bb2da47c67; notion_check_cookie_consent=false' \
--data '{
    "type": "BlocksInAncestor",
    "source": "quick_find_public",
    "ancestorId": "0191bcee-9db0-4c36-90b8-4062af8f12e2",
    "sort": "Relevance",
    "limit": 20,
    "query": "",
    "filters": {
        "isDeletedOnly": false,
        "isNavigableOnly": false,
        "excludeTemplates": true,
        "requireEditPermissions": false,
        "ancestors": [],
        "createdBy": [],
        "editedBy": [],
        "lastEditedTime": {},
        "createdTime": {}
    }
}'

and gets:

{
    "errorId": "519936dd-0928-445f-8a4f-f223acef4a89",
    "name": "ValidationError",
    "debugMessage": "Invalid input.",
    "message": "Something went wrong. (400)"
}

Notion endpoint https://www.notion.so/api/v3/search does not seem to be publicly documented.
I reversed engineer on Notion site by checking what might be considered as an invalid input. The culprit seems to be:
"sort": "Relevance" versus

"sort": {
    "field": "relevance"
},

my bad, the starter kit seems to use an old version of this package. here the query is actually fixed https://github.com/NotionX/react-notion-x/blob/master/packages/notion-client/src/notion-api.ts#L552
