not able to deploy fabric app (rayfin app)

Deployment is still failing with 403 because the issue is with authentication/authorization for the Rayfin CLI, not the tenant toggle itself.

A 401/403 on npx rayfin up is handled as follows:

1. Reauthenticate Rayfin CLI

      npx rayfin login
      npx rayfin up
   

   This refreshes the authentication session used by the CLI.
2. Verify minimum permissions on the Fabric app item Contributors who deploy a Fabric app must have at least Edit permission on the Fabric app item in the Fabric workspace. If only Viewer access is granted, deployments will fail.
3. Confirm the Fabric app workload is enabled in the correct tenant/workspace
   • A Fabric tenant admin must enable Fabric apps (preview) in the Fabric admin portal under Tenant settings → Fabric apps (preview).
   • After enabling, ensure the setting scope (entire organization or specific security groups) actually includes the account being used for npx rayfin login.
   • Use a workspace where contributor or admin permissions are granted.
4. Retry deployment and check status
   • Deploy:

          npx rayfin up
     

   • Check deployment state:

          npx rayfin up status
     

   • If needed, run a dry run to confirm what will be applied:

          npx rayfin up --dry-run
     

If 403 persists after npx rayfin login and confirming permissions, the next step is to validate with the Fabric admin that the Fabric apps workload is enabled for the exact user/group and workspace being used.
