409 error when attempting to download image files
This was working perfectly fine a few days ago when I was testing integration with aibrush.art. Now when my app makes requests for any files ending in .webp or .png, a 409 response is returned with no payload. If I download the corresponding .json file with image metadata, it downloads with no problem. Seems like an api issue.
Well, it has mysteriously stopped happening since I reported it. Someone must have caught the bug and fixed it 🙂
Update - if I rename a file with a .webp or .png extension to end in _webp or _png respectively, the download works.

I'll be happy to help with any issues you're having with the Dropbox API, but I'll need some more information. Please reply with:
- the name and version number of the platform and SDK/library you are using, if any
- the steps to reproduce the issue, including relevant code snippet(s)
- the full text of any error or unexpected output, ideally including any/all headers and bodies for both request and response
Please be sure to redact any sensitive values, such as any access tokens or refresh tokens.
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`;const imageResult = (await this.dropbox.filesDownload({path: `/${imageFileName}`,})).result;
For more context, here is a link to the place in my codebase that has the problem: https://github.com/wolfgangmeyers/aibrush-2/blob/main/src/lib/dropbox.ts#L167

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.I just replied with all of the info you requested but my reply disappeared. Did you get the reply or do I need to repost it?
