Cannot get fields.attachment from issue search

[alfredopalhares]

Before raising any bug be sure that you used the latest release and that it still reproduces with the latest master. No other version is supported.

Describe the bug
I isse has no attachment Id filed, even tough on the web interface I can see them,

To Reproduce
Steps to reproduce the behavior:

  issues_with_att = jira.search_issues(jql_str = 'PROJECT={proj} and attachments is not EMPTY'.format(proj = project_key))
    print(issues_with_att)
    for att in issues_with_att:
        print(att.key)
        print(att.fields.attachment

1. Any additional steps or considerations that happen before or after.

Expected behavior
I should be able to iterate thourgh the fileds.

In this case where 'attachment' is not preset, can specify what fields to get when using the search_issues function.

    issues_with_att = jira.search_issues(
        jql_str = 'PROJECT={proj} and attachments is not EMPTY'.format(proj = project_key),
        fields=["attachment"]
    )
    print(issues_with_att)
    for att in issues_with_att:
        print(att.key)
        print(att.fields.attachment)

I've edited the comment as the fields argument replaces what fields are fetched rather than updating the existing list.

I encountered the same issue and there is a solution:
https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-search/#api-rest-api-3-search-get

Note: All navigable fields are returned by default.

So you have to use fields=['*all'] to get all the fields. Apparently attachments are considered non-navigable.
