 == Debugging the pipeline
 
-Maybe things didn’t go so smoothly for you. Or maybe you're just having a bad day :(. Whatever the case use the flow above to find where in the pipeline things are broken. Then get a bit deeper into that object. You’ll want to test input data at the point of failure. The first question to answer is if the input data is malformed or if the object itself is erring. Decodable’s UI gives you the ability in each pipeline to “Preview” the processing. This is a very powerful debugging tool. Your Astra Tenant has the “Try Me” area where you can set up producing and consuming messages in specific topics. These tools can help you recreate each step of the pipeline and debug issues.

+Follow the data flows described in xref:real-time-data-pipeline/03-put-it-all-together.adoc#following-the-flow[Step 3] to find where in the pipeline things are broken. Decodable is a great visualization tool for this, because you can click through the connections, streams, and pipelines and actually *see* where connections are failing. For example, if you accidentally named a stream "click-stream" instead of "clicks-stream", you can follow the click event to the outbound "clicks-stream" and then to the pipeline, and see that the pipeline is not receiving the message because its inbound stream is misnamed "click-stream". Stop the pipeline, choose the correct stream, and restart the pipeline to get data flowing again.
