Alaister YoungandAlaister Young 820ff0f2d2 fix(studio): handle invalid TanStack API request bodies (#51046)
Malformed JSON now returns `400 Invalid JSON` from the TanStack API
adapter instead of an unhandled 500. Empty JSON bodies and undecodable
cookies follow the existing Next parser behavior.

**Changed:**

- Handle JSON parsing failures before invoking the API handler, while
preserving body-read and downstream handler errors.
- Recognize exact JSON and JSON-LD media types, including case and
charset parameters.
- Keep raw cookie values when URI decoding fails.

**Added:**

- 43 adapter tests covering valid and invalid bodies, cookies, handler
isolation, response headers, streaming, and abort events.

## To test

- POST malformed JSON to `/api/parse-query` with `Content-Type:
application/json`; expect 400 with `Invalid JSON`. Repeat with JSON-LD.
- POST `{"sql":"select 1"}` to the same endpoint; expect 200. This
parses SQL without executing it against a database.
- Repeat the valid request with an undecodable cookie value; expect the
same successful result.
- Open an existing project and database settings; verify normal API
consumers remain usable.

Validation: 59 focused tests, 29 differential body cases plus malformed
cookies against installed Next parsers, Studio typecheck, lint ratchet,
scoped ESLint, formatting, knip, and both framework production builds
passed. Direct local HTTP checks passed for malformed, empty, valid, and
malformed-cookie requests. Next handlers, routes, environment files, and
dependencies are unchanged. Local TanStack browser checks passed for
signed-in project rendering, clean reload, and the untouched support
form. Database settings rendered its error state, but the banned-IP
service returned an upstream connection-timeout payload, so successful
list coverage remains unverified. Chrome blocked direct API-document
navigation; malformed-input behavior is covered by the separate HTTP and
parser checks.

The automatic staging preview ran native Next (confirmed from its build
output), providing an additional Next regression check: malformed JSON
and JSON-LD returned exact `400 Invalid JSON`; valid SQL parsing
returned 200; an undecodable cookie preserved the same valid response.
No SQL was executed. The local TanStack runtime and in-process adapter
checks passed; the combined TanStack deployment results follow.

The combined rollout preview (TanStack, QA commit
`f35b3c42d8ba6a714299b148d797b09107a7a6fe`) also passes deployed
malformed JSON/JSON-LD 400, valid SQL parsing 200, and
undecodable-cookie 200 with the same valid response. No SQL is executed
against a database.

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=
