- [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.core.JsonParseException: Unexpected character (‘{‘ (code 123)): was expecting double-quote to start field name
- [Solved] com.fasterxml.jackson.databind.exc. InvalidDefinitionException: Cannot construct instance of `XYZ` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)
- [Solved] com.fasterxml.jackson.databind.exc. InvalidDefinitionException: Cannot construct instance of `XYZ` (no Creators, like default construct, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information
- [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
