Fixes [sonarly issue #54192](https://sonarly.com/issue/54192) ## Problem Uninstalling an application fails with a DB error when its `packageJsonFileId` / `yarnLockFileId` columns are populated: update or delete on table "file" violates foreign key constraint "FK_3818380258798f9ffa9963b6dc4" on table "application" Storage was also wiped before the failing DB delete, leaving the app half-uninstalled. ## Root cause `application` and `file` reference each other through `ON DELETE RESTRICT` FKs (`application.packageJsonFileId/yarnLockFileId → file.id` and `file.applicationId → application.id`), so no deletion order works on its own. The deferrable-FK migration doesn't help: in Postgres, `RESTRICT` fires immediately even on `DEFERRABLE INITIALLY DEFERRED` constraints (only `NO ACTION` honors deferral). Uninstall deleted file rows first, in autocommit statements. ## Fix `ApplicationService.delete()` now runs in a single transaction: 1. Clear `packageJsonFileId` / `yarnLockFileId` (breaks the FK cycle) 2. Delete the app's `file` rows 3. Delete the `application` row Storage cleanup moved after commit and made non-fatal, so a failure can no longer leave partial state. `deleteApplicationFiles` is split into `deleteApplicationFileRows` (DB, transactional) and `deleteApplicationFilesFromStorage` (blobs). The test cleanup util had the same file-first ordering bug and is fixed the same way. ## Questions / Follow-ups - **Should the FK cycle be resolved at the schema level?** Both legs could be switched to `ON DELETE NO ACTION DEFERRABLE INITIALLY DEFERRED`, which appears to be what the deferrable-FK migration intended — deferral would then actually apply to deletes, making transactional deletion order-independent. Happy to open a separate PR if there's interest. - **Should the marketplace install path set the package file FKs?** It stores `package.json` in the `file` table but never populates `application.packageJsonFileId` / `yarnLockFileId` — today only workspace creation and `application:rebuild-default-deps` set them. Marketplace packages also don't ship a `yarn.lock`, so this needs a product decision. <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22502?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
