ERR Protocol error: expected '$', got ' '

[Flawd]

Getting this error. Why? How fix? I simply execute the code one time, second time, all works fine, third time (just an example) it gives this error. after that the connection is broken.

This is line 38: connection.getJedis().hset(key, field, object.toString());
object is i.e. an integer

Are you sharing a Jedis instance through different threads or something
like that?

bless you you lead me the right way
thank you
you are very generous

i didnt read the manual, only a bad tutorial

the actual error resulted from me chaining an async jedis void into another async void. after that I encountered another error: [B can not be cast to java.lang.Long error, because I always used the same Jedis j = pool.getResource();

...
