Hi @pkastner, and welcome to the community 
I’m very sorry to hear you’re having issues with sending Tweets through n8n. The behaviour might not be related to the problem reported in this thread though. Using Twitter with n8n version 0.150.0 also works fine in principle (this masterpiece of a Tweet was sent out to test this just the other day 
).
Would you be able to share a workflow using which your problem can be reproduced and also confirm if you have any environment variables set? Maybe post this is in a new topic to make sure your question doesn’t get overlooked.
