Jenkins pipeline fail at ssh-add

Hi if you're seeing this - you probably got stuck where I was:

The pipeline randomly fails at ssh-add?
Guess what the fix is - add a new line at the end of your ssh key stored in jenkins, absolutely stupid right.

Here's an example of pipeline:

def tagBuild(gitTag){
	// Required for setup of jenkins slave ssh daemon
    tryAddKnownHost('github.com')
	sshagent (credentials: ['arehmandev-git']) {
	sh("git config --global user.email \"arehmandev@outlook.com\" && git config --global user.name \"arehmandev\"")
	sh("git tag -a ${gitTag} -m \"[JENKINS] Deployment successful of tag ${gitTag}\" ")
	sh("git push -u origin --tags")
}
}


void tryAddKnownHost(String hostUrl){
    // ssh-keygen -F ${hostUrl} will fail (in bash that means status code != 0) if ${hostUrl} is not yet a known host
    def statusCode = sh script:"ssh-keygen -F ${hostUrl}", returnStatus:true
    if(statusCode != 0){
        sh "mkdir -p ~/.ssh"
        sh "ssh-keyscan ${hostUrl} >> ~/.ssh/known_hosts"
    }
}
