Problem:

I am using an <UploadContainer /> with dynamicContent (image) enabled. When testing the module and selecting Feature Image as the dynamic content, I am seeing this error in the console.

Failed to load resource: the server responded with a status of 404 (Not Found)

Interestingly, the error only appears when the module settings modal is open. When the page firsts loads into the Visual Builder the Feature Image resolves and displays normally. It is only after opening the module settings that the error appears in the console.

This error also appears when using the built-in Divi Image module. This makes me think the error is being trigger by the Visual Builder, not by my code.
