dd_lighthouse_integration's Issues

Lighthouse throws "Error: Chrome could not be killed" when running check for multiple instances

Seeing Error pop up in my logs after running this with a few different instances after five or ten minutes:

Unsure what the issue is, maybe this would be resolved by moving over to use lighthouse-batch instead of lighthouse https://www.npmjs.com/package/lighthouse-batch
