processBlobSidecars crashes pre-Deneb #183
Description
Description
Due to a recent PR merged on Lighthouse, the /eth/v1/beacon/blob_sidecars/ endpoint returns an error 400 for slots pre-Deneb. Before it returned an eror 404 which was handled. Goteth should not fetch blobs for slots which do not support it.
