Warum bekomme ich diesen NoCredentialsError bei einem Django-Projekt?

Question

Ich arbeite derzeit an einem Projekt, das auf Django basiert und Wagtail für die Vorlagenverwaltung verwendet.

Ich habe ein Modell erstellt, das ein Streamfield verwendet, das im Grunde ein ähnliches Feld wie RickTextField ist, mit dem Sie vordefinierte oder benutzerdefinierte Blöcke einfügen und in der von Ihnen gewünschten Reihenfolge anordnen können.

Ich habe ein paar benutzerdefinierte Blöcke, die in einfachen HTML-Stücken mit den entsprechenden Platzhaltern besteht.

Wie auch immer, wenn einen bestimmten Block zu verwenden versucht, brüllt es diesen Fehler:

Mein Problem ist, dass das Problem nicht sagen, viel zu mir und googeln hat auch nicht geholfen.

Answer 1

Aus der Sicht des Problems ist das Problem eine Boto (Core) -Ausnahme und nicht unbedingt ein Wagtail-Problem. Könnten Sie überprüfen, ob Botocore und Boto richtig konfiguriert sind?
