Run

Once you’re happy with the steps in Preview, click Run to execute. Felix processes each step in sequence and logs everything as it goes.

​

What happens during a run

Felix executes each step in order. For each step you’ll see:

• Status — running, complete, or failed
• Output — the data or result the step produced
• Log — a record of what the step did and what it received

If your workflow includes a Human Checkpoint, execution pauses at that step and waits for your input before continuing.

​

Reading the output

When a run completes, you’ll see the final output of your workflow — a file, a table, a document, a notification, or whatever your last step produces. You can also expand any step to see its individual output. This is useful for debugging or verifying that intermediate steps processed data correctly.

​

If a step fails

Felix shows you exactly which step failed and why. Common causes:

• Connector not authorised — the connected service needs re-authentication. Go to Connectors to reconnect.
• Missing input — the step expected data from a previous step that didn’t produce it. Check the previous step’s output.
• Description too vague — the step description didn’t give Felix enough to work with. Click the step, update the description, and run again.

You don’t need to re-run the entire workflow after fixing a step. Felix can re-run from the failed step onwards.

​

Run types

From the builder you can run your workflow in three ways:

• Run once — executes immediately on the current input
• Schedule — sets the workflow to run automatically at a set time or interval
• Batch run — processes multiple items through the workflow in one run

See Running for a full guide to each run type.

​

Tips

• Test with a small sample first. Before running a batch of 1,000 documents, run with one to confirm the output is correct.
• Check Human Checkpoint notifications. If a run is paused, Felix will notify you. The run waits until you respond.
• Use logs to debug. If a step produces unexpected output, expand its log to see exactly what data it received and what it did with it.
