Is this also due to restrictive Content-Security-Policy? If yes, do we have a workaround?

Re: Unable to view a pdf file from jenkins workspace

Basically, I cannot open a pdf file on chrome browser from jenkins workspace. If I try opening I get a blank page as you can see in the attached snapshot.

It works fine if I open it outside the workspace though.

Let me know if you need more clarification!

If it's a CSP problem, your browser's debug/network console should tell you.

Note that Jenkins 2.200 has an alternative to CSP for user-generated content (that is not simply disabling it)

Re: Unable to view a pdf file from jenkins workspace

Thanks Daniel!

I checked the browser's console and it shows the following error:

"Refused to apply inline style because it violates the following Content Security Policy directive: "style-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-C7vpsE1KLI7RuUgCprJTQZin6dWK+ccynbOx+OqjVow='), or a nonce ('nonce-...') is required to enable inline execution."

So it does seems to be a CSP problem. When you said alternative you meant that we can relax the rule set right with the help fo this doc - https://wiki.jenkins.io/display/JENKINS/Configuring+Content+Security+Policy

No, but if you actually read today's version of that wiki page it'll point out the alternative
