I am currently at level `NH4` of Kafka.

When I run

`codecrafters submit ` or `codecrafts test`

I see the following error

```auto
Submitting changes (commit: b18bf89)...
push changes: add all files: send-pack: unexpected disconnect while reading sideband packet
fatal: the remote end hung up unexpectedly
Everything up-to-date

```

This is the output for git remote

```auto
git remote -v
origin https://git.codecrafters.io/d30d7ede1d6aa8b6 (fetch)
origin https://git.codecrafters.io/d30d7ede1d6aa8b6 (push)

```

If I manually push I see the following error

```auto
Enumerating objects: 27, done.
Counting objects: 100% (27/27), done.
Delta compression using up to 10 threads
Compressing objects: 100% (19/19), done.

```

Hi @DeshErBojhaa, could you try running the following command and see if it makes a difference?

```bash
git config --global http.postBuffer 157286400

```

This is the output of my `git config --list --global`

```auto
user.name=tamjidahmed
user.email=mail.to.tamjid@gmail.com
commit.gpgsign=true
fetch.prune=true
url.ssh://git@github.com/.insteadof=https://github.com/
init.defaultbranch=main
http.postbuffer=15728640000

```

this is what I see when I try to `git push` or `codecraft test`

```auto

It looks like you’re running into a new issue with large files accidentally committed into the repo. Could you check out this guide and see if it helps?
