Hi,
Welcome to the community!
The sonar.javascript.lcov.reportPaths property takes a comma-delimited list of report paths, so you should be good to go.
As a side note,
This analysis parameter hasn’t been used for years. This is a no-op. You can delete it.
I’m also not sure where you got those sonar.gitlab.* properties, and I’m pretty sure they’re not doing anything either.
HTH,
Ann
