{{Note|The version of Playwright in Nixpkgs and your node developer environment (in <code>package[-lock].json</code>) must match. See [https://www.nixhub.io/packages/playwright nixhub] to see if there is a version that matches npm in nixpkgs, if not you can also downgrade npm's version via <code>npm install playwright@nixversion</code>.
