Hello @wokier,
Welcome to SonarSource community, and thank you for your message !
First of all, I would like to apologize for answering this late. Coming back to your problem, and looking at your pom.xml, it seems that there is a typo in your coverage-related properties. Indeed, you should use the plural form of the properties: sonar.javascript.lcov.reportPaths and sonar.typescript.lcov.reportPaths.
Hope this helps,
Yassin
