I'm writing a custom function that will update a record's "stage" based on an change to a related parent record. The child records are all active in a predefined Blueprint. When I run the custom function to update the "stage" of the child record, nothing happens. For testing, I disabled the Blueprint on the child records, ran the function, and the "stage" field updated as expected. It seems the Blueprint is preventing my custom function from progressing my child records through the Blueprint stages/states.

Is there a method or some syntax I can use in my custom function to bypass the Blueprint or at least invoke the Blueprint transition so that the record moves to the next stage/state?
