twitter got 400 in follower-factory

[mikelty]

The entire error reads:
TwitterHTTPError: Twitter sent status 400 for URL: 1.1/application/rate_limit_status.json using parameters: (oauth_consumer_key=&oauth_nonce=8407703836662294415&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1607558162&oauth_version=1.0&oauth_signature=wkpQTGhB4qpoMvkpmvzUFMfNJ%2Bc%3D)
details: {'errors': [{'code': 215, 'message': 'Bad Authentication data.'}]}
It seems the authentication method or API is no longer valid.
