Request

We need to handle skipped slots that can occur.

Potential Solution

We need to make sure the node is synced when running it in head mode: curl http://localhost:5052/eth/v1/node/syncing -H "accept: application/json".
If a slot has a state but no block, mark it as skipped.
If the slot has no state or block, add it to the known_gaps table.
Handle 404's when querying blocks and state.

We need to make sure the node is `synced` when running it in `head` mode: `curl http://localhost:5052/eth/v1/node/syncing -H "accept: application/json"`. 2. If a slot has a `state` but no `block`, mark it as skipped. 3. If the slot has no `state` or `block`, add it to the known_gaps table. 4. Handle 404's when querying blocks and state. ## Alternative Solutions  # Additional Context
