When there is any error in VarDefinition, the boundary event catches the error and it progresses to 1st ErrorHandle.

But there is an error in Call mrln, instead of progressing to 2nd ErrorHandle, the process ends abruptly.

In my appServices.ts, I use call the below to handle error and its the same for all services:

function handleError(error, context = null) {
    // custom logger & business logic

    return { bpmnError: logMessage };
}

I can't figure out whats wrong?! The diagram seems fine to me.

Could you provide any insight on this? Thank you.

A humble request.

I suppose you are working on many things for the new relase including the below:

error handler fix
allow all scripts to execute async functions including input/output variables
probably the fix for this too

Could you please consider releasing the fix for this error handler thing as a patch asap because the error propogates and all other subsequent tasks have high chances of failing expecially if dependent on that failed task?

Thank you so much.
