Miranda Limonczenko 91b7df64c2 fix(ui): report clipboard write failures instead of rejecting (#50292)
Closes DOCS-1390

## Problem

Sentry [DOCS-AA](https://supabase.sentry.io/issues/7727380816/) reports
`NotAllowedError: Failed to execute 'write' on 'Clipboard': Write
permission denied.` as an unhandled promise rejection.

The error names `write`, not `writeText`, which places it in the
`ClipboardItem` branch of `copyToClipboard`. That branch has two
problems:

- The write runs inside a `setTimeout`, so the surrounding `try/catch`
has already returned by the time it executes. A denied write routes to
the promise's `reject`.
- No caller attaches a `catch`. All call sites either fire-and-forget or
`await` inside an async handler with no `try/catch`, so the rejection
surfaces as an unhandled rejection.

The user-visible effect is worse than the Sentry noise. On that branch
the copy fails with no feedback at all, because the `toast.error` in the
outer `catch` is unreachable from inside the `setTimeout`. The
`writeText` branch does show the toast, so the two paths disagree.

The issue is filed against auth docs, where it surfaced, but the fix
belongs in `packages/ui`. The same branch runs in Studio and www.

## Solution

- Handle the failure inside the `setTimeout`, where it happens: report
it and resolve.
- `copyToClipboard` no longer rejects on either path, matching what the
`writeText` branch already did. No caller relied on rejection.
- Add regression tests for a denied write on both branches.

## Manual testing

1. Run the unit tests. Four `copyToClipboard` cases pass, including the
two new denial cases.

   ```
pnpm --filter studio exec vitest run lib/helpers.test.ts -t
copyToClipboard
   ```

2. Confirm the new test is a real guard. Revert `clipboard.ts` and
rerun. The write case fails with `promise rejected ... instead of
resolving`.
3. Confirm the ratchet is unchanged.

   ```
   pnpm --filter studio run lint:ratchet
   ```

## Summary by CodeRabbit

* **Bug Fixes**
* Clipboard write failures now display an error notification instead of
causing an unhandled rejection.
* Copy operations resolve consistently when clipboard access is denied
or unavailable, including Safari clipboard support.
* Failed copy attempts no longer trigger completion callbacks,
preventing misleading success behavior.

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
