Troubleshooting Haystack Pipelines

Haystack Pipelines are tools that allow users to piece together different components of a question answering system, automating data flow and eliminating computational heavy lifting. However, debugging pipelines can be challenging due to their complexity. To troubleshoot common issues, it's essential to run each component individually to isolate problems, check the error printout for human-readable messages, and visualize the pipeline graph to identify logical errors. By following these solutions, users can simplify debugging and build bug-free programs with Haystack question answering systems.
