- [Solved] com.fasterxml.jackson.databind.exc. MismatchedInputException: Cannot deserialize instance of `XYZ` out of START_ARRAY token
- [Solved] com.fasterxml.jackson.databind.exc. MismatchedInputException: Root name ‘ABC’ does not match expected (‘XYZ’) for type [simple type, class ClassName]
- [Solved] com.fasterxml.jackson.core.JsonParseException: Unexpected character (”’ (code 39)): was expecting double-quote to start field name

- [Solved] com.fasterxml.jackson.databind.exc. MismatchedInputException: Cannot construct instance of `XYZ` (although at least one Creator exists): can only instantiate non-static inner class by using default, no-argument constructor
