2 years ago You're using "schema delegation".
What is happening, is when @graphql-tools/delegate processes the GraphQL request and attempts to forward the Upload scalar value in another request under the hood to the delegated GraphQL API, it's naively attempting to serialize the value as if it's a regular input object, etc. But Upload scalar values represent a file upload stream, and can't be instantly serialized to a JSON value. Think about it… how or why would you convert partly streamed binary file data to JSON text? You can't.
I don't know enough about the particular tools you're using to suggest an exact solution; but the tools should document somewhere how to account for this situation. I've seen GraphQL API gateway solutions correctly re-stream the GraphQL multipart request file uploads before.

I have the same problem with this error, help me please with more information // query mutation mutation Mutation($upload: Upload!) { singleUpload(file: $upload) { encoding filename mimetype } }
