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 "/home/runner/work/_temp/0fff179a-853d-455e-b04e-25cd91c72310/codeql/cpp/tools/autobuild.sh". Exit code was 1 and last log line was: cpp/autobuilder: autobuild summary. 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.

1 issue was detected with this workflow: git checkout HEAD^2 is no longer necessary. Please remove this step as Code Scanning recommends analyzing the merge commit for best results.
