Aspect Ratio in Chat GPT does not work

Generate a tall, vertical image (aspect ratio 9:16) of a hiker standing on a trail in a forest. The scene should be oriented correctly, with the hiker's head at the top of the image and their feet at the bottom. The background should consist of tall trees that extend from the bottom to the top of the image, ensuring that the entire vertical space is filled without any empty areas. This image is intended for a vertical poster, so the scene must fit a vertical layout perfectly.
