How to test 🧪

Reproduction steps

Backups:

• On prod or another branch, create a new cluster
• While the cluster is still provisioning, go to the Database cluster's backups tab
• The Restore button is enabled for the Newest full backup plus incremental option
• Click Restore and then Restore again in the dialog. You should see an error and the loading persists
• Close out of the dialog and open it again. The error and loading state persists

Delete:

• Go to the Database landing table page, ensure you have at least 2 clusters
• Open the network tab and throttle your connection to 3G
• Delete a Database cluster via action menu, then quickly delete the same one again before it disappears from the table (faster if TTC is disabled)
• You should see an error in the dialog. Close the dialog and open the delete dialog for a different cluster. The error persists

Verification steps

Backups:

• Checkout this PR, create a new cluster
• While the cluster is still provisioning, go to the Database cluster's backups tab
• The Restore button is disabled for the Newest full backup plus incremental option with a tooltip explanation
• In DatabaseBackups.tsx line ~318, remove the check for Boolean(unableToRestoreCopy) to enable the restore button
• Click Restore and then Restore again in the dialog. You should see an error and loading should stop
• Close out of the dialog and open it again. The error and loading states should not persist

Delete:

• Go to the Database landing table page, ensure you have at least 2 clusters
• Open the network tab and throttle your connection to 3G
• Delete a Database cluster via action menu, then quickly delete the same one again before it disappears from the table (faster if TTC is disabled)
• You should see an error in the dialog. Close the dialog and open the delete dialog for a different cluster. The error should not persist
