No file route found for slug in deployment

This issue arose when I started my deployment on Render , which simply read as No file route found for slug messageFile The upload page worked fine in development which say it simulated a callback . The upload dropzone does upload files to uploadthing server , but stuck at loading like in the screenshot . Am I doing something wrong ? I set the public url in auth middleware as /api/uploadthing,/api/uploadthing-multi .
