Overview
This node automates browser actions using Playwright, specifically enabling users to take screenshots of web pages. It is useful for capturing visual snapshots of websites for monitoring, testing, or documentation purposes. For example, it can be used to capture a screenshot of a product page to verify UI changes or to archive a webpage's appearance at a specific time.
Use Case Examples
- Taking a screenshot of a full webpage for visual regression testing.
- Capturing a screenshot of a login page to verify UI elements are rendered correctly.

Troubleshooting
- Common issues include browser executable path errors, which can be resolved by installing the required browser using the node's internal setup script.
- Errors launching the browser may occur if the Playwright library or browser binaries are missing or corrupted; reinstalling or updating Playwright and browsers can help.
- If the node fails but 'Continue On Fail' is enabled, it returns an error message with browser type and OS info instead of stopping the workflow.
