Invalid Dangerfile file: undefined method `map' for nil:NilClass

[valeriomazzeo]

When parsing a config file that doesn't have any excluded directory, danger-swiftlint crashes.

Adding the following to my config file fixes the issue.

excluded:
  - excluded_dir

Stacktrace:

[!] The exception involves the following plugins:
 -  danger-swiftlint

Hmm, good catch/fix. Thanks for opening the issue. I'll try to get to this soon but it might be a while, if anyone else is available I'd appreciate assistance 🙇

[valeriomazzeo]

np 👍

[thiagofelix]

@ashfurrow isn't it same issue fixed by #37?

[ashfurrow]

I believe so, @valeriomazzeo could you take a look?

[valeriomazzeo]

Does #37 fix also the case when the excluded key is completely missing?

[ashfurrow]

It should, can you point to the current master and double-check? No worries, we're all busy 😅

[valeriomazzeo]

I am traveling at the moment so won't be able to, until tomorrow :(

[ashfurrow]

No rush – travelling too or else I'd take a look :)

@valeriomazzeo This was probably fixed by #37 .
Can you verify and close the issue?
