Hello,
it is possible to debug in the build environment. What you are likely missing in your project is a scheduler configuration, which includes the bundle you are creating in your code. That's why your callable did not get created and the execute method didn't get triggered.
Just take a look at the samples we provide (for example automation.scheduler). There is the folder "solutions/activeConfiguration/scheduler". In this folder you have a scheduler configuration. You could use a similar configuration for your bundle, but you would have to change the name of the callable in the programs.json (from HelloCallableFactory to your Callable name).
Best regards,
Nick
