I'm facing an issue with my Jenkins pipeline when trying to push changes to a remote Git repository. The error I'm getting is:

Here's the relevant part of my Jenkinsfile:

I'm using Jenkins Kubernetes agents to run this pipeline. The pipeline checks out the repository, updates a values.yaml file with a list of Jenkins plugins, commits the changes, pushes a new branch to the remote repository, and creates a pull request.
I've tried to avoid directly embedding credentials into the URL to prevent security issues. The credentials are managed using Jenkins' withCredentials block.
Despite this, I still encounter the error related to the URL and port number. What could be causing this issue, and how can I resolve it?
Things I've checked/tried:
Any suggestions or insights would be greatly appreciated!
Create a pull request to update plugins from gitops repo
If your USERNAME environment variable contains @ character then that would explain the error. http://[email protected]:[email protected]/git/usernamerepo/devops-gitops-apps.git would result in bob being treated as a user name, gmail.com as a host name, and :Pasw00rd as a port number that is "not a decimal".
Any special characters in both the user name and the password would need to be url-encoded. Or avoided.
To bypass this problem entirely you could use the gitUsernamePassword parameter:
withCredentials([gitUsernamePassword(credentialsId: "${env.GIT_CREDENTIALS_ID}",
gitToolName: 'Default')]) {
sh 'git fetch --all'
}
