Typed Racket unsupported?

I tried to use Typed Racket and it runs locally fine for me (Racket 8.14) but tests are failing online, e.g. for Eliud's Eggs in Racket on Exercism I get

standard-module-name-resolver: collection not found
  for module path: typed/racket/lang/reader
  collection: "typed/racket/lang"
  in collection directories:
   collects

I wouldn’t expect it to be unfortunately.

The track uses the official Racket Docker image, which uses the minimal install. That removes a lot of functionality you might expect out of the box because it provides just enough of Racket for maintainers to build packages. However, that image is about 3.5x smaller than the Docker image for the full install. That lowers the overall cost of the cloud storage for our test runners. Since Exercism relies on donations, we’re obligated to keep operating expenses as low as reasonable across the many tracks we offer.
