## Problem `any[]` type prevented value input: <img width="544" height="349" alt="Screenshot 2026-06-01 at 14 08 47" src="https://github.com/user-attachments/assets/956238d0-6fea-4be1-b75a-ab0e6e6424ac" /> In the workflow Code action (and the Logic Function action), parameters typed as any[], string[], etc. rendered as an empty grey box instead of an "Enter value" text input. After any debounced save, even a properly initialised array field would also collapse into an empty container. The Array<T> / ReadonlyArray<T> generic form fell through to a generic text input by accident (which "looked" right, but for the wrong reason — no schema info downstream). ## Root causes Three places treated arrays as plain objects via @sniptt/guards' isObject (which is true for arrays): 1. WorkflowEditActionCodeFields.tsx — arrays went into the nested-fields branch; Object.entries([]) is empty → empty container, no placeholder. 2. mergeDefaultFunctionInputAndFunctionInput.ts — recursed into arrays during merge, turning [] into {}. Triggered on every debounced save, so the bug surfaced after any edit. 3. get-function-input-schema.ts — only handled T[] (SyntaxKind.ArrayType); Array<T> (SyntaxKind.TypeReference) was unrecognised, so the form lost any item-type info.

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.
