Unable to search for threads raising "#1675036 GraphQL Query Blocked"

[devkarim]

Description of the problem

Unable to search for threads, I've been experiencing this error for an hour now while it was working before.

Code to reproduce

import fbchat as fb
from misc.session import get_session, save_cookies

session = get_session('email', 'password')
client = fb.Client(session=session)
print(next(client.search_for_threads('some user', limit=1)))

Traceback

Traceback (most recent call last):

    (j,) = self.session._graphql_requests(

Environment information

• Python version 3.8.2
• fbchat version 2.0.0a2

No idea why it didn't work today, perhaps some new Facebook updates I guess. Any help?

I'm running into a similar issue when running client.fetchThreadList()

Thanks for the report, this is most likely because we're using a custom GraphQL query that Facebook doesn't support anymore.

Which means we'll have to change it to use the same APIs as the search menu uses.

Initial research shows we could use:

params = {
    "query": query,
    "num_users": 10,
    "num_groups": 8,
    "num_pages": 5
}
(j,) = session._graphql_requests(_graphql.from_doc_id("2268911786543136", params))

With various configurations based on which search_for_X method was called, and maybe combine it with:

params = {
    "search_query": query,
    "result_limit": 3,
    "exclude_ids": [],
    "context": "web_messenger_composer"
}
(j,) = session._graphql_requests(_graphql.from_doc_id("2706854202719826", params))

If we want to search within messages as well?

But theres quite a bit of work needed to do this, since we need to update our parsing methods to handle this new result

@madsmtm hello my freind how to get page, user info using graphql and what is the method to get the doc_id or query_id ??? help me please

The snippets I posted were just notes for myself when fixing this in the future - but I should probably add some documentation about what these Facebook GraphQL internals mean...
