Error in `Airbyte.connections.list_connections` with offset equal to the number of connections available

As described in the following code:
```python
import airbyte

airbyte_workspace = airbyte.Airbyte(
server_url=SERVER_URL
)

response = airbyte_workspace.connections.list_connections(
airbyte.models.operations.ListConnectionsRequest(
workspace_ids=[WORKSPACE_ID],
offset=0, limit=100
)
)
# There are only 20 connections
assert len(response.connections_response.data) == 20

response = airbyte_workspace.connections.list_connections(
airbyte.models.operations.ListConnectionsRequest(
workspace_ids=[WORKSPACE_ID],
offset=0, limit=20
)
)
# Still, with a limit of 20, a "next" page is provided
assert response.connections_response.next is not None

# But it breaks if we try to fetch data from it
airbyte_workspace.connections.list_connections(
airbyte.models.operations.ListConnectionsRequest(
workspace_ids=[WORKSPACE_ID],
offset=20, limit=20
)
)
```
which raises:
