I'm trying to run tests using Karma + HeadlessChrome from an amzn2 AMI (I have a Jenkins installed there). The tests run successful from my local machine, however I'm getting stuck when trying to execute them in Jenkins. I changed the log level of Karma to debug and this is the relevant output:

Following https://github.com/karma-runner/karma-chrome-launcher/issues/137 I'm using Puppeteer:
I've added process.env.CHROME_BIN = require('puppeteer').executablePath() in the karma.conf.js and:
logLevel: config.LOG_DEBUG,
autoWatch: true,
browsers: ['ChromeHeadlessNoSandbox'],
customLaunchers: {
ChromeHeadlessNoSandbox: {
base: 'ChromeHeadless',
flags: ['--no-sandbox']
}
},
I don't know what else I can try, any ideas?
