🛠️ [How-To] Fix “Your flow cannot be found. Flow sys_id:An” Error in Flow Designer
(PRB1828730 Workaround + My Cause: Deactivated Variable)

“Your flow cannot be found. Flow sys_id:An”

…when trying to open a Flow in Flow Designer, and the screen goes grey or unresponsive — you're likely facing a Flow Designer rendering issue. This error can be caused by several things, including:

- Invalid or missing Flow sys_id
- Deleted or unpublished flows
- Broken references in Flow logic
- And in **my specific case**: a **deactivated variable** that was still referenced in the Flow

---

🔍What Happened in My Case

- I deactivated a Catalog Item variable that was being used in a Flow.
- Flow Designer couldn't render the Flow UI properly due to the broken reference.
- This resulted in the Flow UI freezing or displaying the "Flow sys_id:An" error.

✅How I Got Around It (Using PRB1828730 Workaround)

> PRB1828730 documents a workaround where deleting a blocking UI overlay allows you to access a broken Flow in the designer — this workaround doesn’t solve the *underlying issue*, but it helps you *regain access* to fix it.

Here's how:

1. Open Flow Designer and try to load the broken flow.
2. Right-click anywhere on the screen and choose **Inspect** (or press `F12`).
3. In the **Elements** tab, search for:
ReactModalPortal
4. Find this element:
<div class="ReactModalPortal">
5. Right-click → **Delete element**
This removes the UI overlay that blocks access to the Flow editor.
6. Now you can interact with the Flow.
7. In my case, I replaced the reference to the **deactivated variable** with a valid one.
8. Save and **re-publish** the Flow.

💡Notes

- **PRB1828730** is about the workaround (deleting the ReactModalPortal overlay), not about the root cause.
- Your root cause might differ — it could be permissions, a missing Flow, or something else entirely.
- If you’re unsure, check the Flow's references and inputs for any inactive or broken components.
