WorkbenchRunner reports success even when called workspace is terminated – how to stop execution?

Hello,

I have a main FME workspace where I call multiple child workspaces using WorkbenchRunner.

The issue is that even when one of the called workspaces is terminated, the WorkbenchRunner still reports the execution as successful.

My goal is to stop the main workflow immediately if any problem occurs in one of the child workspaces, so that the next WorkbenchRunner does not execute.

What is the correct way to ensure that: If a child workspace fails (error or termination), the main workspace stops immediately, And subsequent WorkbenchRunners do not run?

Any recommended best practice for this scenario?

Thank you.
