should we also make CI also running debug build? This fix is mainly for debug build

[simonhong]

@darkdh We can manually run debug build with CI build option (https://staging.ci.brave.com/job/brave-core-build-pr/job/PR-3233/build)

[darkdh]

yep, I mean we have to trigger debug build after release build is done

[darkdh]

release build passed https://staging.ci.brave.com/job/brave-core-build-pr/job/PR-3233/3/
I triggered a debug build
https://staging.ci.brave.com/job/brave-core-build-pr/job/PR-3233/4/

[bridiver]

ci errors are fixed by another PR and not related to this PR
