Sporadic "Unable to open browser with url: ''"

I run a automatic setup with katalon runetime engine (with a bought license).

I get this error 1/10 times when its running, so its not a constant error so I dont think its a webdriver issue.

Reason: com.kms.katalon.core.exception.StepFailedException: Unable to open browser with url: '' at com.kms.katalon.core.webui.keyword.internal.WebUIKeywordMain.stepFailed(WebUIKeywordMain.groovy:64)

How can I fix this issue? Can I wrap the step in a failure scenario and retry?

Quoting a single line of “Reason: …” is not enough. Please show the full stack trace messages (some hundreds of lines, may be).

And please tell

  • the version of Katalon Studio
  • the version of your browser (Chrome?)
  • the version of your driver (ChromeDriver?)

And possibly we need to look at the .log file of Katalon Studio at:

  • Windows logs folder: \config.metadata.log

  • macOS logs folder: file:///Applications/Katalon%20Studio.app/Contents/MacOS/config/.metadata/log

Katalon version: 7.8.1
ChromeDriver: 92.0.4515.131

But the error was in Firefox and its sporadic. The same test will run fine and then suddenly throw this error.

As @kazurayam has asked, please share the entire stack trace. We need to see all of it.

Unfortunately the log has been deleted but I will comment with a new log when the problem arises again.

Something similar happened and I’ve created a new topic including the logs:
