Command processing stage

Challenges
1

I’m stuck on the commnad processing stage .

I’ve tried creating a new thread for the replica to process command independent of the master.

While , out of the three get commands the first two work as it should but the third command gets a null string . I cannot seem to understand why the replica is unable to process the third set command

Here are my logs:

the problem was ,I wasnt handling Resp arrays correctly and the multiple commands were sent at once .
