Returns a full representation of the issue for the given issue key.

        The issue JSON consists of the issue key and a collection of fields. Additional information like links to
        workflow transition sub-resources, or HTML rendered values of the fields supporting HTML rendering can be
        retrieved with expand request parameter specified.

        The fields request parameter accepts a comma-separated list of fields to include in the response. It can be used
        to retrieve a subset of fields. By default all fields are returned in the response. A particular field can be
        excluded from the response if prefixed with a "-" (minus) sign. Parameter can be provided multiple times on a
        single request.

        By default, all fields are returned in the response. Note: this is different from a JQL search - only navigable
        fields are returned by default (*navigable).
