Incorrect execution order on orchestrator

• Promises do not wait for the code execution.

() => {
    myFunction()
        .then(async function (response) { //Code execution })
        .catch(error => { //Code execution }) 
}

console.log('Finished.')

As in the code shown above, the log function will execute before then the Promise code.
