Title: Relax @IsAWSRegion validation constraint for custom S3-compatible
storage endpoints
Summary: This PR updates the @IsAWSRegion decorator to support
non-standard region slugs (e.g., fr-par) when a custom S3-compatible
storage provider is used.
Previously, the decorator enforced a strict regex
(/^[a-z]{2}-[a-z]+-\d{1}$/) for all region variables, which caused
runtime validation errors and worker crashes when users tried to
configure non-AWS providers like Scaleway or DigitalOcean that use
different region formats.
This change introduces a conditional check: If the property being
validated is STORAGE_S3_REGION and a STORAGE_S3_ENDPOINT is defined on
the configuration object, the strict regex constraint is bypassed, and
any non-empty string is accepted.
Changes Made
is-aws-region.decorator.ts: Updated the IsAWSRegionConstraint class to
accept args: ValidationArguments. Added logic to bypass the regex
validation if args.property === 'STORAGE_S3_REGION' and
object.STORAGE_S3_ENDPOINT is present.
TypeScript Typings: **The AwsRegion interface intentionally remains
strictly typed as `${string}-${string}-${number}`. This preserves strict
compile-time types for standard usage, while class-validator and
class-transformer gracefully handle the runtime relaxation during
environment variable loading.**
Testing
I have added below script to test this function
```
const { validate, ValidateIf } = require('class-validator');
const { IsAWSRegion } = require('./packages/twenty-server/dist/engine/core-modules/twenty-config/decorators/is-aws-region.decorator');
class TestConfig {
constructor(region, endpoint) {
this.STORAGE_S3_REGION = region;
this.STORAGE_S3_ENDPOINT = endpoint;
}
}
ValidateIf((env) => !env.STORAGE_S3_ENDPOINT)(TestConfig.prototype, 'STORAGE_S3_REGION');
IsAWSRegion()(TestConfig.prototype, 'STORAGE_S3_REGION');
const config = new TestConfig('fr-par', 'https://s3.fr-par.scw.cloud');
validate(config).then(errors => {
if (errors.length > 0) {
console.error('Validation failed:');
errors.forEach(err => {
console.error(`Property: ${err.property}`);
console.error(`Constraints:`, err.constraints);
});
} else {
console.log('Validation passed!');
}
});
```

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.
