Unable to Start Atlassian Access Trial

Summary

Admins are unable to start their Atlassian Access trials and are presented with a Blank Page

Steps to Reproduce

1. As an Org Admin, go to ADMIN.atlassian.com
2. Verify a Domain
3. Try to start Atlassian Access trial

Expected Results

Admin is able to start trial and/or is presented with a useful error message as to why the trial cannot be started

Actual Results

Admin is presented with a blank white page with no way to proceed

Digging through the Browser Dev Console, we found an error indicating:
"Status 400 - Admin does not have a valid last name"

Notes

We should present a visible Error Message to the Admin rather than just a blank white screen

Workaround

In this scenario, update your Atlassian account profile to include a valid Last Name
