## Problem
Partner applications **502** for any applicant whose company is already
in the CRM.
The `submit-partner-application` logic function dedupes applicants
**only by person email**. When no person matches that email, it takes
the create path and calls `createCompany` unconditionally. But
`Company.domainName` has a **UNIQUE index**, so whenever a company with
the applicant's domain already exists — which is common, since the **TFT
import seeds companies** — the mutation throws `"duplicate entry"`. The
handler's `catch` returns `{ ok: false }`, and the website
`/api/partner-application` route surfaces it as a **502**. The applicant
can never be submitted.
Real case that surfaced this: an applicant whose company (`BKG
Integration UG`, domain `bkg-integration.de`) was already present from
the TFT import with no Partner/Person attached.
## Fix
Extract `findOrCreateCompanyId`:
- Look the company up by **exact domain** (`domainName.primaryLinkUrl
eq`) and **reuse** it when found.
- Only `createCompany` when no domain matches.
- The matched company is **never renamed** — the existing CRM name wins
over the applicant's free-text `companyName`.
Person-email dedup is unchanged (already handled upstream in the
handler).
### Known limitation
Matches **active** rows only. A *soft-deleted* company still holds the
unique index and would re-collide; clear those with `yarn purge:prod`.
Noted inline.
## Tests
Adds an integration test: pre-seed a company by domain → submit an
application with the same domain → assert the partner reuses the same
company id and the company name is untouched.
## Version
`twenty-partners` 0.5.1 → **0.5.2** (patch: bug fix, no schema change).

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.
