ERROR handleCallbackRequest Failed to register callback result

I've integrated UploadThing in my platform. The client is a NextJS application and the server is a cluster of NestJS microservices.

The issue is that after a successful file upload (on UploadThing the file is present), the onUploadComplete callback is not executed, thus not finishing the upload correctly on the client, because I'm getting:

00:40:26.611 DEBUG handleCallbackRequest 'onUploadComplete' callback finished. Sending response to UploadThing:
ᐉ { "callbackData": {"fileKey":"Yp1sykmpbCf4flJwaXR7axB1jFwdyoRIVZnUlCELh5Xtc9Mm","callbackData":"https://utfs.io/f/Yp1sykmpbCf4flJwaXR7axB1jFwdyoRIVZnUlCELh5Xtc9Mm"} }

Since I'm developing, I've made sure to have the isDev flag to true.

Implementing UploadThing has been almost effortless and I really like it, but there's this error that I can't understand, maybe I'm dumb and forgot something... PLS help, I'm cooked.

Solution

hey - that error you're getting is probably cause you're returning a string from

onUploadComplete

onUploadComplete

. We expect the return to be an object. I've submitted a patch that will type-error when returning primitive values so this will become a compile-time error instead of a surfacing first at runtime https://github.com/pingdotgg/uploadthing/pull/968
