## Problem
When a workflow passes a variable into a text input (e.g. an **AI
Agent** prompt) and that variable resolves to an object or array, the
resolved string contained `[object Object]` instead of the actual
content. The AI then received useless input.
## Cause
`resolveString` in the shared variable resolver builds the final string
with `String.prototype.replace`. When an embedded `{{variable}}`
resolved to an object, the replace callback returned the object
directly, which JS coerces to `"[object Object]"`. The rich-text
resolver had the same issue via `String(resolvedValue)`.
## Fix
When an embedded variable resolves to a non-null object (or array),
serialize it with `JSON.stringify` before inserting it into the
surrounding string. Primitive values keep their existing coercion
behavior, and the single-variable case (`{{message}}` with nothing
around it) still returns the raw object so non-string consumers are
unaffected.
Applied the same guard to both the plain and rich-text variable
resolvers for consistency.
## Tests
Added cases covering embedded object/array variables in both resolvers,
plus a guard test confirming a standalone `{{variable}}` still returns
the raw object.

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

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.
