client.fetch_thread_info doesn't return correct group

[atbuy]

Description of the problem

Before updating to v2, I was able to use

room = {"id": "room id here"}
group_info = client.fetchGroupInfo(room["id"])
participants = group_info[room["id"]].participants
client.set_items(room["id"], participants)

after I updated to v2 ( 2.0.0a5 ) I updated some code to:

room = {"id": "room id here"}

# Error here
# client.fetch_thread_info(room["id"]) returns a wrong group thread.
# this is a generator so it not subscriptable to use client.fetch_thread_info(room["id"])[room["id"]]
group_info = client.fetch_thread_info(room["id"])

How can I get the group with the id that I passed?

Code to reproduce

group_info = client.fetch_thread_info(room["id"])
