error: RPC failed; curl 18 transfer closed with outstanding read data remaining

This error message typically occurs when there is a problem with the network connection between your computer and the remote Git repository. It can be caused by a variety of factors, such as a slow or unstable internet connection, a proxy server blocking the connection, or a firewall blocking the transfer.

To resolve the issue, you can try the following steps:

1. Check your internet connection: Make sure that your internet connection is stable and has enough bandwidth to handle the transfer.

2. Disable any proxy servers: If you are using a proxy server, try disabling it temporarily to see if that resolves the issue.

3. Disable any firewalls: If you have a firewall enabled, try disabling it temporarily to see if that resolves the issue.

4. Increase the timeout value: You can try increasing the timeout value for Git by running the following command: `git config --global http.postBuffer 1048576000`

5. Try cloning the repository using SSH: If you are currently using HTTP to access the repository, try cloning it using SSH instead.

If none of these solutions work, you may need to contact your network administrator or Git hosting provider for further assistance.
