Hi @vadimux,
This error means that your compilation database contains unexpanded response files.
Are you using Cmake? if yes, which version? Have a look at this Unexpanded response file error when using Sonarlint for VSCode - #6 by Abbas. It might be that you changed the CMake version, and those unexpanded response file started appearing.
If you aren’t using CMake, How are you generating the compilation database? Can you share it? I can send you a private message if you prefer to share it privately.
We added support for response file expansion in 6.54 which should be available on SC in a couple of days: [CPP-3572] - Jira.
Thanks,
