Body

#48006 disabled starting mapped tasks from triggerer because it was crashing the scheduler (#47735). It was discovered late in the airlfow 3 beta process so, disabling it was a reasonable choice.

When time permits, one could look into restoring this capability, perhaps with limitations.

Disable starting a mapped task from trigger (#48006)
d264a86 
The scheduler versions of "ExpandInput" classes don't have a "resolve" method anymore so scheduler crashes when trying to expand_start_from_trigger.  To keep the scheduler running, for now we disable the feature.

May be fixed in #48009
