* test(nextjs): Update type cast to integration test

Currently on master tests are failing with:

```
./pages/users/[id].tsx:55:31
Type error: Object is of type 'unknown'.

  53 |     return { props: { item } };
  54 |   } catch (err) {
&gt; 55 |     return { props: { errors: err.message } };
     |                               ^
  56 |   }
  57 | };
  58 |
```

To fix this, we cast err to `Error` type.
