Stage #wa6: error reading from connection

Challenges
1

I’m stuck on Stage #wa6. This runs locally when I run the following command

echo -n "00000023001200046f7fc66100096b61666b612d636c69000a6b61666b612d636c6904302e3100" | xxd -r -p | nc localhost 9092 | hexdump -C

But when the test is run on the server I get this error:

compile] Compilation successful.
Debug = true

Here are my logs:

And here’s a snippet of my code:
Rust Gist

The tests pass when I read everything from the stream, but I haven’t understood the reason of failure here?

Hey @shivamklr, looks like you’ve got past this stage. Do you happen to remember what was wrong? Would love to see if we can improve the tester / instructions.

@badgooooor, could you upload your code to GitHub and share the link? It will be much easier to debug if I can run it directly.
