Playwright fails with Protocol error (Browser.getVersion): undefined

Describe the bug After setting up a sidecar playwright-chrome Docker container as documented in the sample docker-compose.yml I seem to be unable to get Playwright-based fetching to work. When processing a request, the following error is logged:

Protocol error (Browser.getVersion): undefined
