UploadThing Callback Failing on Localhost with useUploadThing Hook

I'm experiencing an issue where UploadThing successfully uploads images, but the callback to my local application fails. As a result, uploaded images are not being reflected in my application's UI. The callback error indicates a transport issue when attempting to POST to http://localhost:3000/api/uploadthing. Error Logs:
