i'm completely new into KNIME and for my paper at my university I need to analyse data for sentiment analysis.
I created a twitter developer account, configured my Twitter API with API Keys etc and execution worked well.
Now I want to mine some Twitter Data with the Node: "Twitter Search". After the configuration of this node, the execution fails with this information :
"Execute failed: 400:The request was invalid. An accompanying error message will explain why. This is the status code will be returned during version 1.0 rate limiting(https://dev.twitter.com/pages/rate-limiting). In API v1.1, a request without authentication is considered invalid and you will get this response.
message - Bad Authentication data."
Could anyone give me a tip for getting this node work properly ?
