Loading images from desktop to Utopia is broken

[Malte]

Specimen 1 observed the following interaction failure: "drag and drop an image to the /public folder (by default Utopia would upload it to the /assets folder), await the end of upload, then drag the image from the file navigator onto the canvas for insertion. image is inserted with the Broken Image icon. trying to load utopia.pizza/p// or utopia.pizza/p//public/ returns a 404 also. this was possibly broken for a very long time"

There are probably a few interlinked issues here, please check that

• S3 upload works
• Utopia (via Remix) can correctly serve local project assets in the public folder, from '/' in the project source code
