Logs and event tracking help you understand what happened during a task run. Use them with page screenshots and a sample of output data to troubleshoot failed runs, incomplete data, unexpected stops, login problems, proxy or User-Agent changes, verification events, and Cloud-run behavior.

What logs are for

Logs can help answer questions such as:
  • Did the task start successfully?
  • Which step failed?
  • Did the page load correctly?
  • Did pagination continue as expected?
  • Was a login or cookie state missing?
  • Did the task extract records?
  • Why did the cloud run stop?

When to check logs

Check logs when:

Troubleshooting workflow

1

Find the failed or incomplete run

Open the task’s run history and select the run you want to inspect.
2

Review the timeline

Look for the first warning, failed action, proxy or User-Agent change, timeout, verification event, or unexpected stop.
3

Compare with the workflow

Match the log event to the corresponding action in the task.
4

Adjust the task

Update waits, selectors, pagination, login, cookies, proxy, or extraction settings as needed.
5

Run a sample again

Test the updated workflow before scheduling or scaling the task. Compare the final page, screenshot, and several output rows with the baseline.

Common causes of run issues

  • Page structure changed
  • Element selector no longer matches
  • Content loaded too slowly
  • Login session expired
  • CAPTCHA or blocking appeared
  • Pagination did not continue
  • Cloud environment differs from local testing
  • The task stopped before reaching all pages

Best practices

  • Review logs after major task changes.
  • Keep a successful run as a comparison point.
  • Test locally when you need to observe page behavior directly.
  • Use cloud logs when scheduled or unattended runs fail.
  • Combine logs with data count and export status to confirm task health.
Logs show what happened during a run, but they may not always explain why a website behaved differently. Keep Cookies and credentials out of exported log excerpts and support tickets. For complex sites, compare Local tests, Cloud logs, screenshots, and the target page structure together.
