get_rows() doesn't work

[AngryMAxxTRO]

Hello everyone!

I cannot get the rows from the connection view. I receive an error "notion.client.NotionValidationError: Invalid input."
My code:

from flask import Flask, request
from notion.client import NotionClient
from var_dump import var_dump

app = Flask(__name__)

@app.route("/index", methods=["GET"])
def index():
    token = "***"
    client = NotionClient(token_v2=token)
    cv = client.get_collection_view(
        "https://www.notion.so/f01a7fa6d9ae4534a3ab9ead602fc2f1?v=c69f8957da6a409380ac02939fb8a58d"
    )

    var_dump(cv.collection.get_rows(search="Doing"))
    return f"some text"

Please, help, where is my mistake?
