This behavior has been observed on the Mekong testnet.

Eg. https://dora.mekong.ethpandaops.io/slot/274010 contains an empty sync aggregate (0% participation)

There are no obvious error logs that could explain this, the only log (from lodestar-geth-3) I found was from our light client server which was complaining about it

Dec-13 17:22:00.136[chain]           debug: sync committee below required MIN_SYNC_COMMITTEE_PARTICIPANTS syncPeriod=33, attestedPeriod=33, syncAggregateParticipation=0

This seems to be isolated to electra / mekong / devnet-4 where it can be observed quite frequently, also has been reported by Luca on discord.
