IndexError when running maws

[jschwartzentruber]

When running maws for the first time, I'm getting this:

$ eval $(maws)
2020-06-08:10:39:21 ERROR    [app.py:1891] Exception on /api/roles [GET]

The login page does load, but is stuck at "Federation in progress..."

If I try to specify the role directly, I get a different traceback:

$ eval $(maws -r "arn:aws:iam::xxxxxxxxxxxxx:role/MAWS-Admin")
Unable to contact AWS : Traceback (most recent call last):

    account_id = role_map.get("aliases", {}).get(account_id, [account_id])[0]
IndexError: list index out of range
$

I'm able to login with this role via aws.sso.mozilla.com without issue.
