[mahmoud-amer-m]

referencing, Issue #28 , Bitbucket cloud always fails with error:
ERROR: Failed to parse JSON: keyNotFound(CodingKeys(stringValue: "user", intValue: nil), Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "danger", intValue: nil), CodingKeys(stringValue: "bitbucket_cloud", intValue: nil), CodingKeys(stringValue: "commits", intValue: nil), _JSONKey(stringValue: "Index 0", intValue: 0), CodingKeys(stringValue: "author", intValue: nil)], debugDescription: "No value associated with key CodingKeys(stringValue: \"user\", intValue: nil) (\"user\").", underlyingError: nil)) ERROR: Dangerfile eval failed at Dangerfile.swift ERROR: Could not get the results JSON file at /var/folders/6q/wgy6jtp12w5gzgm9lzcglpqw0000gn/T/danger-response.json
This PR introduces optional user variable in case the commit email isn't assigned to a bitbucket user

Thank you for the PR :)

Can you please add a test for this change and an entry on the CHANGELOG?

[f-meloni]

I don't think this can be optional, if is a participant it needs a user

[f-meloni]

Same here, you can not make a comment if you don't have a User

@f-meloni Thanks for your review.
I did your comments but I've one question,
could the commit author itself be nil?
because if yes, I'll make author variable also as optional.

[f-meloni]

Ace!

I don’t know the answer, but I think you always have at least the raw value for the author
