Welcome to the new Integration Nation!
so the original question was "how to get the name of the Task that invoked the pipeline and use that value in a mapper snap." given that your suggestion of 'pipe.invoker_name' was invalid, how does one get the task name at runtime?
pipe.invoker_name does not appear to be valid.
is it possible to get the name of the task that initiated the pipeline as a value within a mapper snap?
