Hi guys,

I get an error when I try to change the name/description/other properties of a “Link to another record” column. The error is as follows:  
Cannot destructure property ‘type’ of ‘t’ as it is undefined.

When googling this error message, it seems like its a JavaScript error message. Is this an error on NocoDB’s side or something in my setup (using AlloyDB for Postgres in GCP as the external datasource/db).

Thank you!

We have an internal issue created for this. And the fix should be there EOD or Monday.

Are you using cloud / self hosted ?

I’m still getting this error. (Self-Hosted, just installed today)  
”Cannot destructure property ‘type’ of ‘t’ as it is undefined.”

Did a fix for this come out already?

Problem Example:  
I have Posts and Users.  
Posts with Editor and Creator. So in the posts sheet it has two link columns: “users” and “users”, and I’d like to change the name of the columns.

’users’ belongs to ‘users’  
Foreign Key Column: user\_id

Same on my end, I cannot rename “blue” relation fields (Has Many / reverse links) — `Cannot destructure property 'type' of 't'` error.

**Environment**  
• NocoDB v0.265.1  
• Self-hosted on AWS EC2 (Docker)  
• External PostgreSQL database as data source

**Problem**  
When trying to rename the _blue_ relation fields (the reverse/“Has Many” relation icons) NocoDB shows this error:

```auto
Cannot destructure property 'type' of 't' as it is undefined

```

This happens both:

- in the UI (Grid or Form view → column settings → rename), and

- when using the Meta API:

Regular columns and other relation types (one-to-one / belongs-to) update fine.  
Only the **blue “Has Many”** relations trigger this internal error.

**What I tried**

- “Sync with DB” (resync metadata)

- Re-creating relations with “Link existing column”

- PATCH via both `/meta/columns/{id}` and `/meta/tables/{id}/columns/{id}` endpoints

- Verified the same behavior via API and UI

- Not yet modified metadata directly in SQL (avoiding that for now)

**Expected**  
Ability to rename or patch the display title of reverse/“Has Many” relations without error.

**Example**

One of my relation fields shows the table name instead of the column name, and I can’t change its title.

**Notes / Screenshots**

- Running via Docker (`nocodb/nocodb:0.265.1`)

- External PostgreSQL used as main DB, uuid FKs

- 

@Navi Is there a known workaround or temporary fix for this behavior?

Thanks for brining this to our notice. Issue is happening only with external DB tables. Created an issue here to track it further.
