stream.on error
Hello! 
I just want to understand: does it make any sense?

The first error handler - 
https://github.com/jaydenseric/apollo-upload-examples/blob/master/api/resolvers.mjs#L23
The second one - 
https://github.com/jaydenseric/apollo-upload-examples/blob/master/api/resolvers.mjs#L30
in the same event.
