GraphQl File transfer

Question

Is it possible to transfer a picture from the back to the front as a Upload file? How to transfer file from back to front?

What I did to transfer the image from front to back:

Adding a new data type for a file:

Next, you will need to define scalar Upload in the sсhema.graphqls file:

The most important thing is not to forget to write the method in Mutations in the sсhema.graphqls file:

Look, I get javax.servlet.http.Part when I upload a photo. At the front we get the data through the Apollo hook useQuery/useMutation

But how do I send the photo back to the front?

After all, javax.servlet.http.Part is not transferred to the front? How to write a method signature in the sсhema.graphqls file in Query section and in the implementation of this method in GraphQLMutationResolver implemented class?

I need to transfer the file. If the GraphQl team sees this message, please write more documentation on this topic.
