Hi there, and thanks for posting in the Katalon community! :hugs:

Working with recording, we encourage you trying Katalon Web Recorder Plus: Katalon Web Recorder Plus | Katalon Docs. Double-checking the steps and configurations might resolve the issue.

If the doc doesn’t help, feel free to provide more details, and a community member will assist you soon. Thanks for being a part of our community!

Best,

Why are you using the extension?
What you’re seeing is a known limitation / behavior gap between Katalon Recorder (browser extension) and Katalon Studio (desktop), especially around screenshots.

–> Go for or use Katalon Recorder UI to view screenshots

Or in case you must use extension only then you have 2 options as listed below

  1. Enable automatic failure screenshots

In Studio:

  1. Go to Project Settings

  2. → Execution

  3. → Enable:

    • :white_check_mark: Take screenshot on failure

    • :white_check_mark: Take screenshot on error

This works only for Studio keywords, not Recorder commands.

  1. Use the inbuilt keyword in the script like webUI.takescreenshot()

Katalon Recorder extension screenshots fail—known limitation, no captureEntirePageScreenshot storage in browser UI.

Fixes

  1. View in Recorder UI: Run test → Screenshots tab shows captures (extension limitation).
  2. Studio Settings (recommended):
Project Settings → Execution
✓ Take screenshot on failure
✓ Take screenshot on error
  1. Export . Side file → Import Katalon Studio → Full screenshot support.

Better Alternative

Katalon Studio desktop (not extension):

WebUI.takeFullPageScreenshot()  // Reliable full page

hi @makra

captureEntirePageScreenshot in Katalon Recorder has limited output support. The command executes without error but the screenshot isn’t surfaced in the Recorder UI the way you’d expect. This is a known gap in the extension.

If you need screenshots, switch to Katalon Studio and use WebUI.takeScreenshot('path/to/file.png') instead. That keyword saves the file to disk and attaches it to the test report in TestOps. You can also enable automatic screenshots on failure under Project Settings > Execution.

If you must stay on the browser extension, there isn’t a reliable workaround for captureEntirePageScreenshot. The Recorder extension wasn’t designed to persist or display captured screenshots from that command.
