Hi Dev,

I am stuck at stage: WAIT with multiple commands #na2. I’m not sure how to handle the the replicas who don’t respond with ACk.

I’ve attached logs and the relevant methods below. You can find the full source code [here.](https://github.com/vaibhavhapani/codecrafters-redis-java)

I think no need to handle explicitly, we have time duration for that. But my test is failing. The offset I’m receiving (22) from the first replica should be \>= master offset (31) which is not in this case

am I calculating master offset incorrectly? i’m simply calculating bytes of commands received (SET in this case) and adding it to the master offset i.e. 0 + 31

Hey @vaibhavhapani, could you [upload your code to GitHub](https://docs.codecrafters.io/features/publish-to-github) and share the link? It will be much easier to debug if I can run it directly.

Hi @andy1li, I’ve shared the link in the issue description. Anyways, here you go - [GitHub - vaibhavhapani/codecrafters-redis-java](https://github.com/vaibhavhapani/codecrafters-redis-java)

@vaibhavhapani I tried running your code against the previous stages, but it’s actually no longer passing a previous stage **#TU8 (Replication - WAIT with no commands)**.

 ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/d/d83bf1680a48bf1ce53f7f883ef2c6946f56c6aa.jpeg)

**Suggestions** :

1. Use [our CLI](https://docs.codecrafters.io/cli/installation) to test against previous stages by running:

```auto
codecrafters test --previous

```

1. Focus on fixing the early stages first, as later stages depend on them.

it was passing this stage, maybe because of latest changes it’s breaking. I’ll look into it. But I’m still not sure where it is going wrong in the current stage

Let me know once you’ve fixed the previous stage so I can take another look.

Hey, this is fixed now. Previous stages are working fine. #na2 is still failing.

@andy1li the problem is that I’m getting ACK 22 from the first replica and the master offset is 33 (bytes of the previous command SET foo 123) which is not matching, therefore I’m not counting that and the rest of the replicas don’t send ACK so eventually I’m responding with 0 up to date replicas

the test case expects me to respond with 1

Hi , I found the issue was in how I was propagating the commands to replicas.

```auto
for (OutputStream replicaOutputStream : replicas) {
                writeArray(command.size(), replicaOutputStream);
                for (String arg : command) writeSimpleString(arg, replicaOutputStream);
}

```

I was passing the command args as simple strings rather than bulk strings

✌
