Troubleshooting
Browser dependencies
Playwright does self-inspection every time it runs to make sure the browsers can be launched successfully. If there are missing dependencies, playwright will print instructions to acquire them.
We also provide Ubuntu 18.04 dockerfile and Ubuntu 20.04 dockerfile with the list of Debian dependencies.
Code transpilation issues
If you are using a JavaScript transpiler like babel or TypeScript, calling evaluate() with an async function might not work. This is because while playwright uses Function.prototype.toString() to serialize functions while transpilers could be changing the output code in such a way it's incompatible with playwright.
Some workarounds to this problem would be to instruct the transpiler not to mess up with the code, for example, configure TypeScript to use latest ECMAScript version ("target": "es2018"). Another workaround could be using string templates instead of functions:
await page.evaluate(`(async() => {
console.log('1');
})()`);
Node.js requirements
ReferenceError: URL is not defined
Playwright requires Node.js 10 or higher. Node.js 8 is not supported, and will cause you to receive this error.
Please file an issue
Playwright is a new project, and we are watching the issues very closely. As we solve common issues, this document will grow to include the common answers.
