## Context
After flushing the Redis cache (e.g., via `cache:flush` command), users
get stuck in an infinite loop showing "Your workspace has been updated
with a new data model. Please refresh the page." - refreshing the page
doesn't help.
## Root Cause
When the cache is flushed, `getMetadataVersion()` returns `undefined`.
The version comparison in the error handler then becomes:
```typescript
requestMetadataVersion !== `${currentMetadataVersion}`
// Evaluates to: "5" !== "undefined" → always true
```
This triggers the schema mismatch error on every request, even after
page refresh.
## History
| Date | Commit | What Happened |
|------|--------|---------------|
| Aug 2024 | #6691 (`17a1760afd`) | Introduced the
`${currentMetadataVersion}` template literal that converts `undefined`
to the string `"undefined"` |
| Dec 2025 | #16536 (`0035fc1145`) | Removed the safety check that would
throw an early error when cache is empty, allowing `undefined` to
propagate |
## Fix
Add `isDefined(currentMetadataVersion)` check before comparing versions.
If the server doesn't have a cached version, we shouldn't treat it as a
mismatch - the schema factory already handles populating the cache when
it actually needs the version.
```typescript
if (
requestMetadataVersion &&
isDefined(currentMetadataVersion) && // ← Added this check
requestMetadataVersion !== `${currentMetadataVersion}`
) {
```
## Testing
1. Flush the cache: `npx nx run twenty-server:command cache:flush`
2. Refresh the page
3. Verify no infinite loop occurs and app loads normally

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
