+1. Delete unused projects or databases from your current default Workspace to free up space.
+1. Ensure that you are logged into the correct account in the Prisma CLI. For more details on authentication and account management, please refer to the [Prisma CLI documentation](/platform/platform-cli/commands#authentication).
+1. [Upgrade to a plan](/platform/about#billing) that supports more projects in your default Workspace.
