Hi Batkhuu,

Could you please let us know what the version of the browser is on the load virtual machine? Is this impacting other load tests, or just this one?

Hi Batkhuu,

Could you please check the below:

1. Could you please confirm the Subject7 version you have?
2. Are you using a custom driver? Under Administration > Account Preferences > Drivers, are you seeing "Cloud Executions Chrome Driver (Windows only)" option checked? If checked, what is the custom Chrome driver version?
3. On the 4th tab on Test Plan create/edit screen, replace everything next to Headless option with the below and see if the same issue happens.

javaScriptEnabled=true
chromeOptions=["--start-maximized", "--ignore-certificate-errors","--headless","--ignore-certificate-errors", "--headless", "--disable-extensions", "--disable-translate", "--no-sandbox", "--disable-gpu", "--enable-automation", "--disable-logging", "--disable-infobars", "--disable-dev-shm-usage", "--disable-browser-side-navigation", "--disable-features=VizDisplayCompositor"]

Hi Joseph,

Subject7 version is Platform Fermat 9.2.2.1413

We were using a custom driver for Chrome 91, but after unchecking that and running again, didn't fix the issue.

Using the headless options above didn't help. 

The Chrome version on the VM is 92.0.4515.131

Thanks.

Hi, 

The idea is to match the versions of the driver with the browser. 

"Unchecking" should not fix any issues as it means it will use the default driver of the 9.2.2 version which is 90. 

From what you explained above it looks like the Chrome version on the VM is 92 and the driver used is version 91. 

The best course of action would be to upgrade Subject7 and see if the issue persists or not. If it does persist after the upgrade, please reply on this thread and we will investigate further.
