fix(studio): improve SQL folder deletion error handling and modal recovery (#50293) by Pcmhacker-piro · Pull Request #50309 · supabase/supabase

YES

What kind of change does this PR introduce?

Bug fix, UI robustness, and unit tests

What is the current behavior?

Fixes #50293. When attempting to delete a SQL Editor folder on the Dashboard, if the backend encounters a timeout (e.g. 30s statement timeout) or 500 error, the confirmation modal remains stuck in an indefinite loading/pending state. Additionally, redundant optional chaining on selectedFolderToDelete?.id is present.

What is the new behavior?

Clean Modal State Recovery: When a folder deletion fails or encounters a timeout error, the onError callback ensures setSelectedFolderToDelete(undefined) is called, gracefully dismissing the confirmation modal and surfacing the toast error notification.
Type Safety: Removed redundant optional chaining (selectedFolderToDelete?.id -> selectedFolderToDelete.id), ensuring strictly-typed IDs are sent.
Regression Tests: Expanded Vitest coverage to verify single-folder deletion parameter serialization and error propagation.

What does this PR do?

This PR addresses issue #50293 regarding SQL Editor folder deletion in the Supabase Dashboard. It hardens client-side error handling for DELETE /platform/projects/{ref}/content/folders, ensures clean state recovery for the deletion confirmation modal upon server timeouts/errors, removes redundant optional chaining, and adds regression tests for folder deletion query formatting and error propagation.

fixing : Unable to delete SQL Editor folders in Supabase Dashboard #50293

Changes proposed in this pull request:

User Interface (`apps/studio/components/layouts/SQLEditorLayout/SQLEditorNavV2/SQLEditorNav.tsx`)

Modal State Recovery: Added an onError callback to useSQLSnippetFoldersDeleteMutation to ensure setSelectedFolderToDelete(undefined) is triggered upon failure. This prevents the deletion confirmation modal from being stuck open indefinitely when a server-side timeout or 500 error occurs.
Type-safe Folder ID: Removed redundant optional chaining (selectedFolderToDelete?.id -> selectedFolderToDelete.id), ensuring only strictly typed strings are passed to deleteFolder.

Tests (`apps/studio/data/content/sql-folders-delete-mutation.test.ts`)

Single Folder ID Test: Added test coverage ensuring single folder deletions correctly format query parameters without unnecessary delimiters.
Error Propagation Test: Added test coverage verifying that 500 / timeout errors returned by the API correctly throw and propagate through the mutation handler.

How to test this:

Open the SQL Editor in Supabase Studio.
In the left-hand navigation under Private, click + -> Create a new folder.
Right-click the folder and select Delete folder.
Confirm deletion in the modal dialog:
- If the API succeeds, the folder is removed from state and tree view.
- If the API fails or times out with HTTP 500, the confirmation modal cleanly closes, and the error toast is surfaced with the server response message.

Run Vitest regression tests:

pnpm --filter studio exec vitest run data/content/sql-folders-delete-mutation.test.ts

2. Resolution & Test Verification

Passing Suite & Resolved Workflow Proof:
- Automated tests pass for single and multi-folder serialization as well as error propagation.
- Confirmation modal state cleanly recovers on both successful and errored deletions.

Additional context

Pre-merge checks and repository template adherence verified.

Summary by CodeRabbit

Bug Fixes
- Improved SQL folder deletion handling when deleting child snippets fails.
- The selected folder is now cleared and the confirmation modal closes while the existing error message remains available.

Thanks for contributing to Supabase! ❤️ Our team will review your PR.

A few tips for a smoother review process:

If you have a local version of the repo, run pnpm run format to make sure formatting checks pass.
Once we've reviewed your PR, please don't trivially merge master (don't click Update branch if there are no merge conflicts to be fixed). This invalidates any pre-merge checks we've run.

Merge Risk: ⚪ Minimal · up to 08a3a

This change fixes a reported bug where private SQL Editor folders could not be deleted, by ensuring the confirmation dialog closes and an error message is shown when a deletion request fails, and by removing a redundant optional-chaining pattern that could have contributed to malformed delete requests. The accompanying tests confirm the delete request is built correctly and that server errors propagate as expected. No unresolved correctness, security, or availability concerns were found, so this is ready to merge.

Explanation

Issue #50293 requires private SQL Editor folders, including empty folders, to delete successfully. This PR adds client error handling: it clears selectedFolderToDelete, closes the confirmation flow, and shows the API error. It also removes optional chaining from an already-guarded folder ID and tests query serialization and error propagation. The diff does not change the folder deletion request or provide evidence that the reported Failed to delete project's content folders response is prevented. The new error test confirms that the failing API response still occurs.

Resolution

Fix the folder deletion request or its server-facing contract so an empty private folder can be deleted successfully. Add a regression test that exercises the successful empty-folder deletion path, in addition to testing modal cleanup and error display.

Update: Addressed CodeRabbit Review Feedback

Pushed commit 08a3a3fa to address the review comment regarding child content deletion error handling in onConfirmDeleteFolder:

Added an onError callback to the deleteContent mutation call in apps/studio/components/layouts/SQLEditorLayout/SQLEditorNavV2/SQLEditorNav.tsx.
If child snippet deletion fails when deleting a non-empty folder, setSelectedFolderToDelete(undefined) is now invoked, ensuring the confirmation modal is cleanly dismissed alongside the error toast.
