I didn't encounter this error and didn't change the default buffer size, I just gathered useful resources and shared the output of the sample running react-todo on heroku. Please be careful in troubleshooting and backup your project.
Below I list the most relevant resources on the subject.

Demo application react-todo: https://github.com/serdarsen/react-todo
According to most sources I've read, this issue occurs when trying to send a very large file. For testing purposes I'm using ubuntu 22.04 and my demo application named react-todo. We can fallow steps below.
- Turn on git debug logging (Please check second resource for windows configuration)
srdr@asus:~/dev/react-todo$ export GIT_TRACE_PACKET=1
srdr@asus:~/dev/react-todo$ export GIT_TRACE=1
srdr@asus:~/dev/react-todo$ export GIT_CURL_VERBOSE=1- Check heroku remote is https
srdr@asus:~/dev/react-todo$ git remote -v

heroku https://git.heroku.com/serdarsen-react-todo.git (push)
origin [email protected]:serdarsen/react-todo.git (fetch)
origin [email protected]:serdarsen/react-todo.git (push)- Check http.postBuffer and increase it (for react-todo I didn't change the default)
