Jenkins environmental variables on config yaml file

Question

we have jenkins file with below Env variable. When we are trying to integration the docker compose and the config yaml file is not getting the value of the jenkins env variable instead its taking the variable name. Can some one help here what we are doing wrong

jenkins file:

        stage('Run tests') {
                steps {
                    withEnv([
                        "PASSWORD=${env.TEST_DB_CREDS_PSW}",
                        "USER=${env.TEST_DB_CREDS_USR}",
                    ]){
                    sh '''#!/bin/bash

                    {
                        cd atests 

                        docker-compose down
                        kill $$

Config.yaml:

dbconfig:

    dbuser: ${USER}
    dbpass: ${PASSWORD}
    dbname: 
    dbdrivername: 
    tablename:
