@ngraziano, thank you for your changes.
@ARMmbed/mbed-os-maintainers please review.

Thanks @ngraziano for the contribution. Our teams will review.

This PR is fixing #7863 ?

[ngraziano]

It should fix #7863 (You make me discover this issue).

But when reading #7863 (comment) , I see there is other improvement that can be added to the pull request :

• I may change ${workspaceRoot} to ${workspaceFolder} (see VSCode Variables Reference)
• I may change \\ to / on windows configuration to make easier to read.

Do I have to complete this PR or create another one ?

[0xc0170]

Can complete it if you have time now, while we review - adding separate commits. As these will be simple fixes
