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.

      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?
