What is VS Code Error Code 128?
VS Code Error Code 128 is a Git-related exit code indicating a command failed. It typically occurs due to authentication failures, incorrect repository URLs, or missing SSH keys, preventing the editor from communicating effectively with your remote repository provider.
Step-by-Step Solutions to Fix Error 128
Method 1: Update Git Credentials
The most common cause is outdated or incorrect credentials stored on your system. You need to clear the cache so VS Code can prompt for a fresh login.
On Windows, search for “Credential Manager” and remove entries related to GitHub or GitLab. On macOS, use “Keychain Access” to delete your Git credentials.
Method 2: Verify Remote URL and SSH Access
Ensure your project is pointing to the correct repository address. A typo in the URL often triggers the 128 exit code.
Run this command in your VS Code terminal to check the current remote configuration:
git remote -vIf the URL is incorrect, update it using the following command, replacing the placeholder with your actual URL:
git remote set-url origin https://github.com/username/repository.gitMethod 3: Reset Git SSH Keys
If you are using SSH instead of HTTPS, your local machine might not be authorized. You must ensure your SSH agent is running and contains your key.
Add your private key to the agent using this command:
ssh-add ~/.ssh/id_rsaTest the connection to GitHub specifically to confirm access is granted:
ssh -T [email protected]Method 4: Fix Permission Issues
Sometimes the error occurs because the folder permissions prevent Git from writing to the .git directory. This is common in shared environments.
Try marking the directory as safe in your global Git configuration:
git config --global --add safe.directory "*"
