Impossible to create webdriver session with direct connect on and with parallel test run

[kekero4ka]

Steps to reproduce:

gecko-driver: 0.21.0 gulp-protractor: 4.1.0 protractor: 5.4.0 node: 10.5.0

Firefox config:

 baseUrl: config.frontendUrl,
    capabilities: {
        browserName: 'firefox',
        'moz:firefoxOptions': {
            args: [
                '--headless',
                '--single-process'
            ]
        },

        shardTestFiles: true,
        marionette: true,
        maxInstances: 4
    }

---

But during test run I get:

[11:20:34] I/testLogger - 
[11:20:34] E/launcher - Runner process exited unexpectedly with error code: 1
[11:20:34] I/launcher - 4 instance(s) of WebDriver still running

Any update here in the future? I'd love to have Protractor running my specs in parallel, but so far I've had no luck. Is it due to the directConnect option here? I'm not getting the error that's displayed above, but I can't for the life of me figure out what else it could be.

I suggest to not use direct connect with parallel runs. Just setup selenium-server and connect to it

[adamtaylor13]

Very well. Thanks for the direction.
