Exception:com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException. What should I do?

Looks like Jackson found a JSON field that could not be mapped to the object it is being deserialized to. What does this mean? Think of JSON just having keys and values. Now, if you look at any class, it is very similar - a class may have a field with a particular variable name, and this field can have value.
Please make sure to check your POJO file and map the fields accordingly.
