Hi, Guys

I was trying to run k6 in linux ubuntu virtual machine and I encounter an error while executing the browser instance script in a headless mode.

aut@LMAUT1:~$ ./k6 K6_BROWSER_ENABLED=true run script.js
ERRO[0000] unknown command "K6_BROWSER_ENABLED=true" for "k6"
aut@LMAUT1:~$ K6_BROWSER_ENABLED=true ./k6 run script.js

Thanks for your help.

  • Increase the timeout value in the chromium.launch() function to a higher value, for example, 120s, to allow more time for the page to load.
  • Check the URL https://qa9.legalmatch.com/ is accessible and responding correctly. Check if the page is functional and not blocked by any firewalls or security settings.
  • If possible consider reducing the number of VUs to see if the issue persists.

Hi, @nehakakar

This issue was fixed, I workaround with other test servers and it’s working fine. Thank you for your suggestions.
