Changelog Entry

Description

We're currently using npx playwright@1.49.1 run-server inside a Docker container based on the official mcr.microsoft.com/playwright:v1.49.1-noble image. This image already includes preinstalled browser binaries under /ms-playwright.

Executable doesn't exist at /root/.npm/_npx/xyz/node_modules/playwright-core/.local-browsers/chromium...

Proposed Change:

To avoid unnecessary browser reinstallation and fix these runtime errors, we propose explicitly setting the following environment variable in the Docker Compose configuration

PLAYWRIGHT_BROWSERS_PATH=/ms-playwright

This ensures Playwright will use the preinstalled Chromium at /ms-playwright (as intended by the base image) rather than looking in a temp directory.

Added

  • Environment variable PLAYWRIGHT_BROWSERS_PATH=/ms-playwright in Docker Compose to explicitly define the browser installation path.

Changed

  • Runtime behavior of npx playwright@1.49.1 run-server to ensure it uses the system-installed Chromium from /ms-playwright instead of attempting temporary browser installs.

Fixed

  • Resolved issue where Playwright attempted to use non-existent or temporary browser binaries, resulting in errors like:
    Executable doesn't exist at /root/.npm/_npx/.../.local-browsers/chromium_headless_shell...
