3 errors and 1 warning

Canceling since a higher priority waiting request for PR Check - Autobuild direct tracing (custom working directory)-refs/pull/3203/merge exists

The operation was canceled.

Cannot build an overlay database because build-mode is set to "autobuild" instead of "none". Falling back to creating a normal full database instead.
