@shohanr there’s another error I got when visit a hasMany relationship field in record Details.

## Feature(s) impacted

Cannot show hasMany relationship field.

## Observed behavior

We have a sender model and an account\_sender model. The latter belongs to sender (one-to-many relationship). When I visit the account\_sender field in sender record `Details` tab and there’s no account\_sender under it, it works correctly. But when there are account\_senders belonging to the sender, I got following error in console:

```javascript
Error: Expected id to be a string or number, received null

```

and the UI is like:

 ![Screen Shot 2022-10-06 at 12.24.30 pm](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/d/d74d5f66b16ac97af285a799b5848c6df91a6a5a.png)

account\_sender has no `id` column in the table.

## Expected behavior

No error. Show a list of account\_senders.
