search_blocks not working?

[emmby]

from notion.client import NotionClient

if __name__ == "__main__":
    client = NotionClient(token_v2=...)
    print(client.get_top_level_pages())
    print(client.search_blocks(search='foobar'))

Printing get_top_level_pages() works fine.
Printing search_blocks(search='foobar') results in a 400:

Traceback (most recent call last):
