Fehler im Firebase-Cloud-Funktionsdokument-Trigger bei Verwendung von V2-Funktionen: Fehler beim Dekodieren von Protobuf ⇐ JavaScript

[Anonymous]

Ich migriere mein Firebase Cloud Functions-Projekt von v1 auf v2.
Da Authentifizierungstrigger in v2 noch nicht verfügbar sind, habe ich immer noch Authentifizierungstrigger in v1 – aber alle meine Firestore-Trigger sind jetzt v2.
Einer meiner Firestore v2-Trigger schlägt beim Aufruf sofort mit folgendem Fehler fehl:

Code: Select all

Direkt darüber ist auch dieser zugehörige Fehler protokolliert:

So ist mein Trigger geschrieben (v2):

Code: Select all

exports.onPrivateUserDataUpdateTrigger = onDocumentUpdated(
"PrivateUserData/{docId}",
async (event) => {
logStartOfFunction("onPrivateUserDataUpdateTrigger");
// other logic
logEndOfFunction("onPrivateUserDataUpdateTrigger");
}
);
