# Fix cursor-based pagination with lexicographic ordering for composite
fields
## Bug
The existing cursor-based pagination implementation had a bug when
handling composite fields.
When paginating through results sorted by composite fields (like
`fullName` with sub-properties `firstName` and`lastName`), the WHERE
conditions generated for cursor positioning were incorrect, leading to
records being skipped.
The previous implementation was generating wrong WHERE conditions:
For example, when paginating with a cursor like `{ firstName: 'John',
lastName: 'Doe' }`, it would generate:
```sql
WHERE firstName > 'John' AND lastName > 'Doe'
```
This is incorrect because it would miss records like `{ firstName:
'John', lastName: 'Smith' }` which should be included in forward
pagination.
## Fix
Create a new util to use proper lexicographic order when sorting a
composite field.

This PR has several objectives:
- Ignore invalid and empty links in the frontend
- Ignore empty links when creating or updating a link field in the
backend
- Throw an error when trying to create or update a link field with an
invalid link
The logic is mostly the same in the frontend and the backend: we take
the initial primaryLink and the secondaryLinks, we discard all the empty
links (with `url === '' || url === null`), and the primaryLink becomes
the first remaining link.
## Frontend
There are three parts in the frontend where we have to remove the empty
links:
- LinksDisplay
- LinksFieldInput
- isFieldValueEmpty; used in RecordInlineCell
## Backend
I put the logic in
`packages/twenty-server/src/engine/core-modules/record-transformer/services/record-input-transformer.service.ts`
as it's used by the REST API, the GraphQL API, and by Create Record and
Update Record actions in the workflows.
