Why it happens

The repository was cloned and detected correctly, but the Dockerfile deployment failed while starting the application. The command runner reported Syntax error: "(" unexpected, which commonly means a Bash-style command was executed by /bin/sh, or a generated command was malformed. The exact command is not included in the captured log.
