This is likely result of changes on Twitter's side related to changes to their twitter API endpoint and not directly related to the ConsumeTwitter processor included with NiFi:

Looks like free access to consume from Twitter was cut off in February.
From the following page, we can see that the Free tier now only allows writes and no consumes.

You would need at least a "Basic" subscription to continue to consume from Twitter.
