Exception on evaluator - Prelude.last: empty list #21

Closed utdemir closed 5 years ago

utdemir commented 5 years ago

Hi,

One of my repos started failing to evaluate, as shown in the screenshot:

I don't remember what I did, but it might be about some GitHub permissions; however currently the permissions look ok.

Hi Utku,

Thanks for reporting! This is actually a bug in the agent. Do you think it's feasible to use attribute sets instead of a list in ci.nix? Doing so will fix the problem for your project and provide a better experience in the UI. You may need to use pkgs.recurseIntoAttrs, but only if you're going to nest attribute sets.

As to why it stopped working: older versions of the agent only looked at default.nix, so it seems that an update of the agent has broken your project by picking a different file.

Hi @roberth.

Thank you for the quick answer. I modified the ci.nix to return an attribute set instead of a list and the issue is resolved :).

Thank you very much.
