TeamCity Solution Engineering / Packer Templates Build 665 outcome was FAILURE
Summary: Build stopped: Script exited with non-zero exit status: 1; build stopped: Image failed to build due to error; exit code 137 (Step: Image Publish (Command Line)) Build time: 00:05:10

Would it be possible to get access to the build log? Could be interesting to learn how such a small change can impact the build this badly :)
