Import buttons don't work

[malemburg]

I'm tying to import an export made using mongo express, but the logs always show:

mongo-express  | TypeError: Spread syntax requires ...iterable[Symbol.iterator] to be a function
mongo-express  |     at exp.importCollection (file:///app/lib/routes/collection.js:512:16)
mongo-express  |     at Layer.handle [as handle_request] (/app/node_modules/express/lib/router/layer.js:95:5)

mongo-express  |     at param (/app/node_modules/express/lib/router/index.js:365:14)

and the browser gets a 400 back.

I have tried this with the import buttons on the collections page, as well as the import buttons on the individual collections. Both show the same behavior.

I've tried this with the 1.0 and 1.0-20 docker images. Both have the same problem.
