No such property: USERNAME for class: groovy.lang.Binding

I have issues with my block code - "withCredentials([usernamePassword(…it doesn’t recognize the usernameVariable and also the passwordVariable when I am using double quotes.

example jenkinsfile:

parameters {
credentials(name: 'APP_CREDS', defaultValue: 'APP_CREDS', credentialType: "Username with password", required: true, description: "Credentials")

}


withCredentials([usernamePassword(credentialsId: 'APP_CREDS', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) {
                        env.APP_USER = "${USERNAME}"
                        env.APP_PASSWORD = "${PASSWORD}"
                    }

Example error output:

withCredentials already adds the items to the environment, you don’t really want to assign them to env.XXXX because they could leak. Instead you use the variables inside a shall script call or similar, by referencing the variable names you specified in the withCredentials (e.g., USERNAME and PASSWORD). If you want them to be called APP_USER and APP_PASSWORD, then you would change the usernameVariable and passwordVariable values.
