Hello!

We tried to add a job to our CI build but it hangs in “Queued” state and never completes.  
Can you help us to figure out, what is the problem?  
The link to the build:  
[https://travis-ci.com/Backendless/Flutter-SDK/jobs/259052035](https://travis-ci.com/Backendless/Flutter-SDK/jobs/259052035)

Best Regards,  
Maksym

> 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](https://docs.travis-ci.com/user/build-config-validation), it should be warning you about such stuff.
