Error in heartbeat function
See original GitHub issueWhen using the launcher, we encounter an error in the heartbeat function
[20:01:01] TypeError: Cannot read property 'title' of undefined
at Timeout._onTimeout (/home/travis/build/ampproject/amphtml/node_modules/karma-sauce-launcher/dist/launcher/launcher.js:36:20)
at listOnTimeout (internal/timers.js:549:17)
at processTimers (internal/timers.js:492:7)
Relevant snippet:
// Heartbeat function to keep alive sessions on Sauce Labs via webdriver JSON wire calls
const heartbeat = () => {
pendingHeartBeat = setTimeout( (driver) => {
log.debug('Heartbeat to Sauce Labs (%s) - fetching title', browserName)
driver.title()
.then(null, (err) => {
log.error('Heartbeat to %s failed\n %s', browserName, formatSauceError(err))
clearTimeout(pendingHeartBeat)
return this._done('failure')
});
heartbeat()
}, 60000);
}
I’m not sure how driver
could get set; I’m not familiar with setTimeout providing any arguments to its callback. Should this be trying to read from connectedDrivers
or something similar?
