In the world of software development, working with Git is a daily routine for many developers. One common error encountered during a `git push` operation is the cryptic message: "RPC failed; result=22, HTTP code = 411." Understanding what triggers this error and how to resolve it can significantly streamline your workflow.

Understanding the Error

What does RPC failed; result=22 signify?

This error message originates from the Git transport layer. RPC stands for Remote Procedure Call, a protocol that one program can use to request a service from a program located on another computer in a network. When this fails, it means that the communication between your local repository and remote repository couldn't be conducted properly.

  • Result Code 22: This is a generic error code indicating an incorrect configuration or a failed transmission.
  • HTTP Code 411: This HTTP status code is specifically related to the size of the payload. It indicates that the request refuses to continue because the server requires the Content-Length header field in the request, but it was not specified.

When Does This Error Occur?

  • Pushing Large Amount of Data: The error is more prevalent when attempting to push large repositories or many files at once.
  • Server Requirements: Some servers require specific headers or configurations to handle the request, and if those aren't present, the request will fail.
  • Proxy Settings: Misconfigured proxy settings can also intervene in the communication path, causing this error.

Resolution Steps

Several methods can be used to resolve this issue. Here are some of the most effective ones:

1. Configure Git to use a smaller HTTP post buffer

Sometimes, large pushes can cause issues due to limited buffer sizes. You can adjust this by setting a larger buffer value:

  • Always ensure that your local configuration aligns with your team's workflow or organizational settings.
  • If you are frequently pushing large changesets, consider integrating repository management tools or hosts that provide adequate support for large pushes.
