Hi @gnl42,

Thanks for reaching out. This is a bug, so I’ve created THIS ticket and it will be fixed in the next release.

The cause of that issue was that Taint Vulnerabilities were found on SonarQube, and SonarLint wanted to show them in the editor - but no file with such a Taint Vulnerability was opened, but we assumed there was.

Best,
Tobias

NOTE: in my case it’s still reproduced, SonarLint is connected to SonarCloud and the exception is still in the console.

Hi @lrozenblyum,

the release has not yet happened, so the issue was not fixed.

Best,
Tobias

Hi @lrozenblyum, Hi @gnl42,

the newest version of SonarLint for Eclipse 10.3.0.82013 was just released, there will be a Community announcement following soon.

This issue was fixed in that release.
