Sandbox FAQ
How do I delete the sandbox projects created in the DoiT Console?
Sandbox projects that were created in the DoiT Console need to be deleted in your Google Cloud console. You cannot delete them from within the DoiT Console itself.
Note
You will need the Project Deleter permission at the project level to delete a sandbox project.
Why do some sandbox projects not belong to an organization?
It is possible that your organization was created after the sandbox project was created, meaning there was no organization that it could be attached to.
With the Organization Viewer role, you can run the following command in CloudShell if you want to see when your organization was created:
gcloud organizations describe NAME_OF_YOUR_ORG
