# Troubleshooting workflows
In this lesson, you'll learn how to use the run log, Parabola AI, analysis branches, and the follow-the-data technique to debug and investigate any workflow — so you can unblock yourself and your teammates quickly.
***
Use the troubleshooting techniques from this lesson to analyze and validate your flow's data quality.
```text wrap theme={null}
Add row numbers in the first column after my join step.
```
If the new step rearranges your canvas layout, click the **Auto-layout** button in the bottom right to tidy everything back up.
Your canvas layout may look different after clicking Auto-layout — that's expected. The important thing is that the steps are connected correctly.
Pick a row number and trace it upstream and downstream. Click into the step just before the join, find that row, then open the step just after the join and look up the same row — you can see exactly what columns were added and whether the join matched correctly.
The steps added to your canvas and their exact documentation may differ from what you see below — every AI response is unique. The important thing is that your resulting data set matches what you see here.
