Python: Modul-App kann nicht in AWS Lambda importiert werden

Question

Ich habe die Datei app.py im Stammverzeichnis meiner app.zip-Datei. Und die Funktion Handler auch richtig definiert (lambda_handler), nach dem Handler Config .: app.lambda_handler

Dennoch erhalte ich die Fehlermeldung: Unable to import module 'app': No module named app

Wo habe ich falsch gemacht?

Versuchen Sie, die Protokollausgabe zu überprüfen. Es gibt Ihnen mehr Informationen als der Fehler, den Sie oben gesehen haben.

Schließlich erinnern, dass Sie die Python 2 Syntax benötigen, ersetzen Anrufe wie:

print number_of_words von print(number_of_words)
