Go to the page where this workflow runs. Open it by clicking preview on the editor mode so you’ll be already on the debug_mode (or you can just enter on the page and add “?debug_mode=true” at the end of the url parameter.
Select step-by-step option on the debugger and trigger your workflow (for instance, if its starts when a button is clicked, just click on the button).
You’ll then be able to run each step of your workflow. Go to the step where a slug is created and check the values, so you’ll be able to better understand whats happening and also review it together with the other steps.
Or you can just go to your workflow tab, select the event, then select the step you want to inspect (create slug) and click on “add a breakpoint in debug mode”.
Then open the app with debug mode on and run the workflow, it’ll go directly to the selected step so you can investigate whats happening.
