Travis job hangs, waiting to be queued

[native-api]

Jobs stuck on "Queued."

This happens if you request a nonexistent environment. In this particular case, dist: doesn’t accept a list – so you end up requesting something like dist: '["bionic", "xenial"]'. You need to write: matrix: include: - dist: bionic - dist: xenial

In your case, language: doesn’t accept a list so you end up requesting nonexistent language: "['generic']".

If you enable build config validation, it should be warning you about such stuff.
