Hi @florian_ec , thank you for your patience. Your problem might be related to this other thread. I see in your sonnar-scanner command you are using the correct coverage parameter but, could you check that in your CI you are not using the deprecated sonar.typescript.lcov.reportPaths and instead the sonar.javascript.lcov.reportPaths?
You can read more in our documentation.
Please, let us know if this is helpful for you or if you would need anything else!
Best regards,
Antonio
