I have reinstalled Sentry from scratch now with SENTRY_SINGLE_ORGANIZATION set as False and ran into new problems.
There are no users in sentry database to begin with and I’m unable to register. When I created a new user by logging into sentry-web pod and tried to login, I ran into new issue “You do not have access to any organizations within Sentry.”:
From sentry_organizations table I can see that sentry organization exists but I’m somehow unable to access it.
When I try to navigate to /organizations/new to create another organization, there is still a very brief error message Unable to save your changes. Please ensure all fields are valid before continuing.
In sentry-web logs there are no errors visible.
Update: By navigating into Admin → Organizations → Sentry I can create new projects and teams under Sentry-organization, but there is still no way to create new organizations.
