A part of our code only has access to the Node/Express req object.
However, we need to access the Koa Request and/or Koa Context.
Does Koa inject the Context into the Node req object at all?
(Additional context: we're using Koa Multer together with S3 Multer, and S3 Multer only provides req in its callbacks, since it was obviously designed for the original Multer library.)
