Hi @neshkeev
I got exactly the same error when was trying to follow the instructions "how-to-dotty-scalajs.md"
https://gist.github.com/sjrd/e0823a5bddbcef43999cdaa032b1220c

Did you fine a solution for it, or can you point me to a ticket/(or anything else) where is talking about this?
I appreciate any help from the start

@FabioPinheiro , the test has to be fixed. There is no separated issue, if a fix is trivial then you can fix without an issue, otherwise it would be great if you found the root cause and create an issue. The fix is optional
