UnhandledPromiseRejectionWarning: Unhandled promise rejection selenium_server_logs.log.lck #4241
Description
Hi there,
I'm currently using the following configurations:
- Node Version:
v6.9.1 - Protractor Version:
5.0.0 - Angular Version:
1.5.11 - Browser(s):
Chrome 54.0.2840.100 - Operating System and Version
CentOS Linux release 7.2.1511 (Core)
-selenium-server-standalone-2.53.1.jar
A sample of my protractor configuration is the following:
seleniumServerJar: './node_modules/protractor/node_modules/webdriver-manager/selenium/selenium-server-standalone-2.53.1.jar',
localSeleniumStandaloneOpts: {
args: ['-log', './Results/selenium_server_logs.log', '-debug'],
jvmArgs: [
'-Dwebdriver.gecko.driver=./node_modules/protractor/node_modules/webdriver-manager/selenium/geckodriver-v0.12.0.exe',
'-Dwebdriver.ie.driver=./node_modules/protractor/node_modules/webdriver-manager/selenium/IEDriverServer_Win32_2.53.1.exe'
]
},
I run a suite of tests which produce the following output:

(node:4209) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: ENOENT: no such file or directory, lstat '/home/jenkins/workspace/ACA_System_Test_Smoke_Dev/Results/selenium_server_logs.log.lck'
In this case this throws an unhandled PromiseRejectionWarning which terminates the process ungracefully. This only occurs when I specify the logging settings:
localSeleniumStandaloneOpts: {
args: ['-log', './Results/selenium_server_logs.log', '-debug'],
},
Now this only occurs from time to time about 3 runs out of 10 and without logging this never occurs. In addition, this only occurs when I encounter a failed scenario. It is also worth noting when a scenario fails in the After hook we reset the browser using calls
browser.restart();
browser.get(browser.baseUrl);
so to get the browser back to a known state. Has anyone seen this issue occur before? Many thanks in advance & apologies if I'm posting this issue in the wrong repository location.
