ninja: build stopped: subcommand failed.
[0 more errors; see full log]

Full log here.

The log link shows no errors found when build check. No other reference for the reported error. This looks like an ALI-CI infrastructure/cache issue rather than a compilation error from the commit.
The failure comes from gRPC connection errors to the local action cache at localhost:8980
(Socket closed / Connection refused / Connection reset by peer), while downloading/querying cached build artifacts.
I do not see a C++ compilation error in this excerpt.
Thus I will enable the auomatic merge since the pending check is success and the pr waited for several weeks.
