Running Playwright in Heroku

See original GitHub issue

Today we are running pupeteer in Heroku by using this buildpack: https://github.com/jontewks/puppeteer-heroku-buildpack

When trying to deploy with playwright with the trivial webkit example (the one described in this repo) I get the following error:

(node:4) UnhandledPromiseRejectionWarning: Error: WebKit revision is not downloaded. Run "npm install" or "yarn install"

Certainly node_modules dependencies are installed otherwise the error would be different. Any ideas what would be missing?

I will keep debugging, but any hint might be useful.

@diervo The https://github.com/jontewks/puppeteer-heroku-buildpack is doing some magic, like installing dependencies. However, webkit requires a different set of dependencies to run, e.g. check out our github workflow.

My bet would be that there’s a need for a new playwright-heroku-buildpack that adds all the dependencies necessary for all three browsers.

I ssh in the dyno and all dependencies and paths seems to be there (playwright-core/.local-chromium/linux-733125/chrome-linux)

Also, can you check that there’s also playwright-core/.local-webkit and playwright-core/.local-firefox folders with binaries? Can you also try running binaries there? (for webkit, please run pw_run.sh --headless)

All of them seem to fail.
