Sonarly Claude Code 5ad4387f96 fix: handle undefined flow state gracefully in workflow run side panel
https://sonarly.com/issue/34209?type=bug

When viewing a workflow run record page, the side panel crashes with "Expected the flow to be defined" because `WorkflowRunVisualizerEffect` resets `flowComponentState` to `undefined` during data refetch while the side panel that depends on this state remains open.

Fix: Replaced `useFlowOrThrow()` with `useAtomComponentStateValue(flowComponentState)` in `SidePanelWorkflowRunViewStepContent` and added `!isDefined(flow)` to the existing null-check guard that already handles `workflowRun` and `workflowSelectedNode` being undefined.

**Why this fix:**
The `flowComponentState` is set by `WorkflowRunVisualizerEffect` via a `useEffect` that depends on async GraphQL data. When the workflow run data is temporarily unavailable (network errors, refetch cycles), the effect resets `flowComponentState` to `undefined` without closing the side panel. The side panel component was using `useFlowOrThrow()` which throws when flow is undefined, causing a crash.

The fix follows the exact same pattern already used on line 68 of the same file:
```typescript
if (!isDefined(workflowRun) || !isDefined(workflowSelectedNode)) {
  return null;
}
```

Now extended to also check for flow:
```typescript
if (!isDefined(flow) || !isDefined(workflowRun) || !isDefined(workflowSelectedNode)) {
  return null;
}
```

This renders nothing (graceful degradation) while the flow data is loading or temporarily unavailable, and re-renders automatically when the Jotai atom is populated — matching how the component already handles the other async dependencies.

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 deploy

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.
