I’m stuck on Stage #HB5.
I’ve used the implementation in this repository for the decoding process. However, it wasn’t enough to pass the tests. What I found strange is that my Redis server had the same outputs as the official Redis server (see the figure below). There seems to be nothing wrong with the decoding implementation. Are the test cases correct? Thanks for reading my post.
I think I’m running into the same issue. Here is the output I get, you can find the code here: GitHub - andrea-berling/rediz: A Redis implementation in Zig, for learning and fun

I’m having this issue, too.
We’re looking into this – thanks for reporting everyone!
Our tests do pass against Redis so this’ll be an interesting one to nail down

Maybe it is connected with reducePrecisionForBulkString in remote tests?
Maybe error tolerance of (± 1e-06) is too strict?

No, test are not passing against Redis.

Hi Everyone! We’ve upgraded our tester to include a fix for this test case here.
Please give it a re-try and let us know how it goes.
