I’m trying to run a very basic script in playwright-java, just a simple browser launch and visiting a site. Since it is the very first run of any playwright script on my computer, it is first trying to download the browsers and while doing so I’m getting an error that reads “UNABLE_TO_GET_ISSUER_CERT_LOCALLY”, have pasted below the entire error message.

I tried running the same script on another computer and it worked perfectly fine. The machine on which I’m trying to run has Zscaler installed, and after searching the internet for the solution I found out the Zscaler indeed is causing issue here.

However unable to find any solution till now, how do I install the playwright browsers? I would appreciate your help on this issue. Thanks!

Following is the error stack trace
