scalajs-env-jsdom-nodejs run fails with UnsupportedInputException

Question

I'm trying to put together a very simple project. It compiles, but when I try to run it, it fails with:

[error] org.scalajs.jsenv.UnsupportedInputException: Unsupported input: List(CommonJSModule(/home/esgott/Repos/onlyco/target/scala-2.12/scalajs-bundler/main/onlyco-fastopt.js))

The project code is at https://github.com/esgott/onlyco. I am stuck at debugging this issue, do you have a clue?

Answer 1

When using scalajs-bundler, as you seem to be doing, it is not enough to specify jsEnv to be a JSDOMNodeJSEnv. Instead, as the reference documentation says, you should use the following scalajs-bundler-specific setting:

requireJsDomEnv in Test := true
