@rahul1990gupta Thanks for highlighting the issue! We’ve fixed it via this PR . In the meantime, you can try to verify whether you have parsed topic_id correctly. If you are not sure, feel free to provide a link to your code on GitHub, then I can take a look at it for you.

Thanks @andy1li for your quick response. I see that error message has changed there, but still showing error. Here is the link to the code in python. rahul1990gupta/codecrafters-kafka-python/blob/master/app/main.py import socket # noqa: F401 import struct import threading import u…

@rahul1990gupta Thanks for sharing the code! Would really appreciate it if you could also include the changed error message. :handshake:

@andy1li [image] This is the error message. there are two things that i am failing compact_record_length should be zero topic_id should match. they looks same on the terminal. So, maybe its a format(byte vs str) issue. any help is appreciated. thanks.

compact_record_length should be zero Let me dig deeper into compact_record_length, and get back to you later. topic_id should match. they looks same on the terminal. So, maybe its a format(byte vs str) issue. @rahul1990gupta Well, the outputs prefixed by [decoder] just tell us how the teste…

@nblaisdell2 I don’t have access to your code, but the error message from your screenshot seems exact the same to Rahul’s. Could you look at my response to him above, and try to explain briefly how you’re parsing topic_id? (Pretend I’m a rubber duck, as in Rubber duck debugging .)
