Debug e ripetizione delle esecuzioni non riuscite

Even well-built automations fail sometimes — an app changes, data is malformed, or a service is down. The difference between a fragile and a reliable workflow is how quickly you can find and fix the cause.

Strong debugging skills turn mysterious failures into quick fixes.

Every automation platform keeps a history of runs. Each entry shows when the workflow ran, whether it succeeded, and how long it took.

This log is your starting point: scan it to spot failed or stalled runs.

Click into a failed run to see each step laid out in order. Successful steps are marked clearly, and the failing step is highlighted, usually in red.

This pinpoints exactly where the workflow broke.

For each step you can inspect its input data (what it received) and output data (what it produced).

Comparing these often reveals the issue: a missing field, an empty value, or data in an unexpected format.

The failing step shows an error message from the app or platform. Common ones include authentication failed, required field missing, or invalid value.

Read the message carefully — it usually names the exact problem and field.

Most failures fall into a few buckets:

• Broken or expired app connections
• Missing or wrongly mapped fields
• Data type mismatches, like text where a number is expected
• Third-party outages or rate limits

To confirm a fix, you need to reproduce the failure. Note the exact input that caused it, then run the step or workflow again with that same data.

If it fails the same way, you have a reliable test case.

Most platforms let you replay a failed run after you fix the cause. The workflow re-executes with the original data, so you do not lose the event that triggered it.

Replay turns a failed run into a successful one without waiting for the trigger to fire again.

Rather than rerunning the whole workflow, you can often test a single step in the editor. Feed it sample data and check the output instantly.

This tight feedback loop makes finding the right fix much faster.

If a bug caused many runs to fail, fixing it leaves a backlog. Some platforms let you replay failed runs in bulk so all the affected events are processed at once.

This recovers lost work without manual one-by-one effort.

Debugging is reactive; prevention is better. After fixing a failure, harden the workflow:

• Add filters to skip bad data early
• Validate required fields before critical steps
• Add error handling so one failure does not stop everything

Test your understanding of debugging and replaying runs.

You learned to debug and replay failed runs:

• Use the execution history to find failed runs
• Inspect each step's inputs, outputs, and error messages
• Reproduce the issue, fix it, and replay the run
• Test single steps for fast feedback and replay in bulk to clear backlogs
• Harden workflows afterward to prevent repeat failures

Confident debugging keeps your automations dependable.
