User list does not include custom fields

[glowinthedark]

Describe the bug

The command slackdump -v -list-users -r json does not include the custom fields in user profiles.

For example, a request of the form
https://SUBDOMAIN.slack.com/api/search.modules?_x_id=1111111-11111111.551&_x_csid=2222-33333&slack_route=12345678&_x_version_ts=ABCDEFGH&_x_gantry=true&fp=7d

returns profile data in the form

}

The key fields is not present in the output of slackdump -v -list-users -r json.

Is there a way to have those fields included? What would need to be changed in the code in order to get that data?

I've checked the API and it doesn't appear that one can fetch the custom fields using the bulk API call to get all users. I'll have a look.
