How to pass extra variables to ansible playbook running in a Jenkins pipeline

Question

Here is the pipeline code that I want to execute from Jenkins

pipeline{
    agent { label 'ansible' }
    stages{
        stage('SCM Checkout'){
            steps{
                git branch: 'karthick-test', credentialsId: '9153d6ae-fc0c-4242-a83a-cdc932bd23b4', url: 'https://itstash.xyz.com/scm/myansible/myansible-ansible.git'
            }
        }

        stage('Playbook Execution'){
            steps{
                ansiblePlaybook colorized: true, credentialsId: 'gcs_ssh_key', disableHostKeyChecking: true, extras: '–-extra-vars \'\"targets=${targets}\"\'', installation: 'Ansible', playbook: 'playbooks/check_cpu_usage.yml' }
        }
    }
}

After executing the code from Jenkins, "SCM Checkout" is functioning properly but "Playbook execution" is failing with below error:
