JsonParseException: Unrecognized token '': was expecting ('true', 'false' or 'null')

On the redis-cli, when I run: hgetall id:3bb536598d71 I see

 1) "id"
 2) "\"811\""
 3) "item"
 4) "[{\"id\": \"4429\", \"validity\": {\"startDate\": \"2018-12-06T00:00:00\", \"endDate\": \"2018-12-08T23:00:00\"}]"
 5) "show"
 6) "true"

But when I run:

Config config = new Config();
config.useSingleServer().setAddress("redis://127.0.0.1:6379");
RedissonClient client = Redisson.create(config);

RMap<String, Object> map = client.getMap("id:3bb536598d71");
map.readAllEntrySet().forEach(System.out::println);

It is throwing an exception.

It appears the field and value of the hash do not have the same encoding scheme. The field seemed to be plain string whereas value were encoded as JSON strings. So trying to decode the plain string field with JSON decoder would no doubt fail since it is not a valid JSON string.

You need to find what JSON is actually being parsed. Run the application within a debugger, set a breakpoint on the relevant constructor for JsonParseException … then find out what is in the ByteArrayInputStream that it is attempting to parse
