This error occurs when Jackson, a JSON processing library in Java, is unable to serialize or deserialize an object of type java.io.FileDescriptor. This is because FileDescriptor is not a simple type that can be directly converted to JSON.
The error message indicates that the root cause of the problem is an InvalidDefinitionException, which is usually thrown when Jackson is unable to find a suitable serializer or deserializer for a given type. The nested exception message should provide more details about why the definition of the type is invalid.
To resolve this error, you may need to create a custom serializer and deserializer for the FileDescriptor class, or convert it to a simple type that can be easily serialized and deserialized. Alternatively, you can exclude the FileDescriptor field from the JSON conversion process by using annotations or configuration settings.
