I have tried interactive feature in following ways:

a) Simply adding interactive to tasks:

It does nothing.[1][2]

b) Setting interactive to 'true':

It does nothing as well but this message is logged: 'Running task interactive...' [3][4]

c) Using interactive_on_error or interactive-on-error:

Throws " No module named 'tasks.interactive_on_error' " [5][6]

Please let me know if I have used them correctly.
