Intermittent IllegalStateException: Unknown opcode 5 while running JS tests
sjrd opened this issue · comments
This issue was initially reported in Scala.js upstream at scala-js/scala-js#3201. We assumed for a long time that it was a bug in the generic testing infrastructure of Scala.js, but recent investigation suggests that the problem is in uTest, with an incorrect usage of the messaging protocol (understandably, since it is poorly documented).
If the investigation is correct, changing this line to return None would fix the issue.
