IndexError: tuple index out of range

Beginne mit _appmap/event.py ungefähr bei Zeile 509 und dem Pfad zur Ausnahmebehandlung in _appmap/instrument.py. Reproduziere den Fehler, indem du den Fall test_derivatives aus test_zeta_functions.py von SymPy v1.0 ausführst. Als erledigt gilt die Aufgabe, wenn der gemeldete IndexError bei der Behandlung dieser Ausnahme nicht mehr auftritt und der Test abgeschlossen wird.
