neo773 b0dc637dbd Throw proper error on duplicate emailing domain (#22790)
Adding an emailing domain that already exists blew up with a raw
QueryFailedError and the client just saw a generic "An error occurred".
The unique index on domain is global, so the workspace-scoped existence
check never caught rows owned by another workspace.

Now the check is unscoped and throws an EmailingDomainException mapped
to CONFLICT with a proper user-facing message, in both the
createEmailingDomain mutation and the email group channel flow. Also
dropped the hardcoded catch-all snackbar on the new channel page so
server messages actually reach the user.

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.
