Recommended action: Pre-populate the selenium cache (~/.cache/selenium) or put a matching driver in PATH / specify its path explicitly; otherwise allow network access or configure a mirror/proxy. Option: Pre-populate the selenium cache (~/.cache/selenium) or put a matching driver in PATH / specify its path explicitly; otherwise allow network access or configure a mirror/proxy. [evidence: official_recommended_action] Applies when: Selenium 4.6+ in a sandbox without internet, with offline mode enabled (SE_OFFLINE / --offline) Steps: 1. Install a chromedriver/geckodriver matching the browser and put it on PATH (or set the driver path in Service) 2. Or warm the ~/.cache/selenium cache during image build while online 3. Keep SE_OFFLINE=true only when the cache/PATH is populated Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
