Ignored the logicalType property ("timestamp-millis"). It should probably be nested inside the "type" for the field.

{"name": "leaving", "type": ["null" ,"long"], "logicalType": "timestamp-millis", "default": null, "doc": "leaving timestamp"}

{"name": "leaving", "type": {"type": ["null" ,{"type": "long", "logicalType": "timestamp-millis"}]}, "doc": "leaving timestamp"}

InvocationTargetException: No type: {"type":["null",{"type":"long","logicalType":"timestamp-millis"}]}
