Salesforce Flow Error: Packaged Flow Label Does Not Exist

While working with a Salesforce 2GP managed package screen flow (such as one for managing pledge changes), you may encounter an intermittent error that looks like this:

Error element in 2 GP managed package flow (FlowScreen).
Flow does not exist. Check spelling.

This error can be confusing—especially when it disappears after a few minutes or affects only some records. Let’s break down what’s causing it and the workaround solutions available.

🧩 The Root Cause

This issue originates from referencing a custom label from a managed package directly in a Screen Flow. These flows—typically part of a 2 GP Managed Package Flow—sometimes fail to resolve labels at runtime due to metadata caching issues in Salesforce.

Salesforce has acknowledged this as a known issue, which can intermittently prevent managed package labels from loading properly.

🔄 Why It Happens:

It doesn’t affect all records or users—only a few at a time.
It usually resolves automatically after some time.
The root cause is Salesforce’s internal label caching, especially with 2GP managed packages.

✅ Workaround Solutions

Until Salesforce provides a permanent fix, here are two reliable workarounds:

1. Quick User Fix: Clear Cache and Refresh

If the issue occurs for a particular pledge or user:

Ask the user to clear their browser cache.
Refresh the record or screen.
Try again after waiting a minute or two.

This often helps because the cache refresh triggers reloading of the missing components.

2. Stable Fix: Clone the Managed Package Flow and Localize the Labels

If the issue persists or you need a more scalable fix:

Clone the affected Managed Package Flow (e.g., Change Pledge Flow).
In the cloned version:
- Replace any label references from the managed package with local custom labels defined in your org.
Save and activate this local flow version.

This gives you full control and removes reliance on Salesforce’s runtime label resolution for managed packages.

🎯 Summary

This label resolution issue is a known caching problem in Salesforce when using Managed Package Flows. If you see this error:

🟢 Try clearing the cache and refreshing the page as a quick fix.
🛠️ For long-term stability, clone the flow and replace managed labels with local ones.
