Twitter API authentication error

[AngusVeitch1]

I’ve been using the Twitter API connector almost daily for several months without issue, but today the Twitter Search and Twitter Timeline nodes immediately return this error:

Execute failed: Server returned HTTP response code: 401 for URL: https://api.twitter.com/1.1/application/rate_limit_status.json?include_entities=true&tweet_mode=extended

I have tried regenerating the access codes and even created a new API app, but to no avail. I’ve also restarted my computer and re-synced the clock. I also updated my Knime extensions, which I notice included updates in the Twitter and Google connectors category.

I can’t find any evidence that other people are suddenly running into this problem, but I thought I’d check in case it might be a Knime-specific issue (e.g. if Twitter has changed their API and Knime’s connector no longer works).

In any case, I’m out of ideas, and I really need this to keep working. So any help would be greatly appreciated.

Hi there @AngusVeitch1,

seems another user experienced same and it ended up being issue on Twitter’s side.

ERROR 401 in Twitter node

hi, from this morning I receive an error from my KNIME-Twitter node (in prod from last year): ERROR Twitter Search: Execute failed: Server returned HTTP response code: 401 for URL: https://api.twitter.com/1.1/application/rate_limit_status.json?include_entities=true&tweet_mode=extended I try also to regenerate my access tocken and others keys.

Br,
Ivan

Looks like you’re right - it was at Twitter’s end. I have since heard one other report of API issues occurring at that same time. And it’s all working for me again now. Cheers.
