Steps to reproduce
role is “”
Error Code: ModelOptionsUtils$mapToClass
public static <T> T mapToClass(Map<String, Object> source, Class<T> clazz) {
try {
String json = OBJECT_MAPPER.writeValueAsString(source);
return OBJECT_MAPPER.readValue(json, clazz);
} catch (JsonProcessingException var3) {
JsonProcessingException e = var3;
throw new RuntimeException(e);
}
}
**Solution **
Set at program startup
ModelOptionsUtils.OBJECT_MAPPER.configure(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true);
