Summary

Documents the new HEADLESS_BROWSER_SCREENSHOT_TIMEOUT_MS env var that makes the previously hardcoded 180s screenshot readiness timeout configurable.

Changes

  • Added HEADLESS_BROWSER_SCREENSHOT_TIMEOUT_MS row (default 180000) to the headless browser environment variables table in self-host/customize-deployment/environment-variables.mdx.
  • Added an operator note warning that the headless-browser container's own session timeout (e.g. browserless v2 TIMEOUT) must be ≥ this value, otherwise it becomes the binding limit.

Context

Source PR: lightdash/lightdash#25399feat(backend): make screenshot readiness timeout configurable.
