I’m using sonarqube 8.9 LTS and checking a CSS code the analysis tell me that there is a blocker bug on this code

print-color-adjust: exact;

with this message

Unexpected unknown property “print-color-adjust”

But that property exist for CSS as you can see here

Any suggestion? Thank you very much in advance

Hi,

Welcome to the community!

Your version is past EOL. You should upgrade to either the latest version or the current LTS at your earliest convenience. Your upgrade path is:

8.9.* → 9.9 → 10.0 (last step optional)
