ConversionException mit Retrofit und Gson

Question

Ich arbeite mit Retrofit und Gson Converter, aber ich bekomme diese seltsame Ausnahme. Ich verwende zwei URLs, um den Anruf auszuführen. In beiden Fällen führe ich den gleichen Aufruf aus und erhalte die gleiche Antwort auf der Ebene der vollständigen Protokolle, aber eine der URLs gibt mir diese Ausnahme und ich kann die Daten im zweiten Fall nicht analysieren.

Verwenden von Retrofit v1.9 und Gson v2.6.1.

Danke!

Ihre Gson Objekte sind wahrscheinlich falsch. Sie können generate Java classes based on your JSON for GSON.
