Installing Add-ons Directly from Marketplace Does not Work

Summary

When trying to access the Marketplace Site and start a Free Trial for an add-on in Cloud, it will not allow the user to have it installed once redirected to the instance again.

Steps to Reproduce

1. Go to https://marketplace.atlassian.com
2. Search for an add-on to be installed
3. Click on Free Trial and it will redirect the user to the instance
4. The add-on installation process will keep spinning and no results will be retrieved

Expected Results

The add-on installation should give a popup for the user start using it

Actual Results

The installation process keeps spinning.

The below exception is thrown on the console::

Uncaught TypeError: Cannot read property 'subscriptionAnnual' of undefined

Workaround

(If there is no workaround directly say so)

Instead of going directly to https://marketplace.atlassian.com the user should access the Manage Add-ons page inside the Confluence Administration. Specifically, the Install new Add-ons option (https://example.atlassian.net/wiki/plugins/servlet/upm/marketplace)
