We were unable to automatically build your code. Please replace the call to the autobuild action with your custom build steps. Encountered a fatal error while running "/opt/hostedtoolcache/CodeQL/2.27.1/x64/codeql/csharp/tools/autobuild.sh". Exit code was 1 and last log line was: Error: Could not auto-detect a suitable build method. See the logs for more details.

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