Maximum Call Stack Size Exceeded Error

Issue

An organization may encounter an error of Maximum call stack size exceeded when attempting to deploy a pipeline. The logs will show the call stack increasing in size until reaching some arbitrary limit. The pipeline will not deploy correctly.

Cause

This error means that somewhere in the pipeline code, a function or stage is being called which in turn calls another function  or stage and so forth, until you hit the call stack limit. An example would be a pipeline Json that has an incorrect dependancy, such as a stage that depends on a non-existing stage.
