Beginne mit RestCodec.restToArgs in RestCodec.java und verfolge die Parameterverarbeitung bis zu FormProcessorCreator$PartProcessor.getValue, wie im Stacktrace gezeigt. Untersuche, wie die Ausnahme beim Parsen der Anfrage zum protokollierten Fehler wird, und identifiziere die relevanten Tests oder den Pfad zur Fehlerbehandlung. Als erledigt gilt die Aufgabe, wenn der gemeldete Fehler das Problem mit dem Anfrageparameter klar beschreibt.
