Thanks for the help!
I'm using the "dropbox" npm package version 10.34.0.
Here's a code snippet that shows the `Dropbox` instance being used to download the image file:
const imageFileName = `image_filename.png`;

Response Headers:
If I change the file name to end in "_png" instead of ".png" and then download it, I get a 200 response and it downloads fine. Same happens with .webp files. The .json files that I'm using to store image metadata download without any issues.
