That looks like you haven't applied the migrations needed. Per the release notes, that upgrade will require database migrations: https://fusionauth.io/docs/v1/tech/release-notes/

As a reminder, you can have fusionauth do the database migrations, but only if you are in development mode (check fusionauth.properties). If you are in production mode, you'll have to apply the migrations yourself, as outlined here: https://fusionauth.io/docs/v1/tech/installation-guide/upgrade/#database

FYI a lot more FusionAuth Cloud details are available in the cloud installation guide.

Added missing db migration notices for 1.21.0 and 1.22.0.

Once you make the purchase, you will be given a license id. You’ll enter that license id into your self-hosted FusionAuth under the Reactor menu item. This will activate your license and enable all of the premium features.

If you also purchase an Edition that comes with support, you’ll see a new menu item on your account in the FusionAuth website. This will let you open support tickets or provide you with our support phone number if you have an emergency.
