Chore Door project

I am currently on the “Chore Door” project of “building interactive javascript websites” section of the web development path. After completing the tenth step, the image should change and the ChoreBot should be visible, but that is not happening. I can’t figure out the error in my code. Here is a link to the website -
https://www.codecademy.com/paths/web-development/tracks/build-interactive-websites/modules/web-dev-interactive-websites/projects/chore-door

And I have pasted my code below -

let doorImage1 = document.getElementByID(‘door1’);
let botDoorPath = “https://s3.amazonaws.com/codecademy-content/projects/chore-door/images/robot.svg”;
doorImage1.onclick = () => {
doorImage1.src = botDoorPath;
}

Please help !
