Electra /eth/v2/validator/aggregate_attestation returning 404s for DENEB

[Bez625]

When testing the current proposed lighthouse version for Electra on holesky (deneb) we always get a 404 when calling /eth/v2/validator/aggregate_attestation.

Lighthouse version:

Lighthouse v6.0.1-62a0f25
BLS library: blst
BLS hardware acceleration: true
SHA256 hardware acceleration: true
Allocator: jemalloc (4K)
Profile: release
Specs: mainnet (true), minimal (false), gnosis (false)

Example curl:

curl --header "Content-Type: application/json" --header "Accept: application/json"  --request GET --data '' "http://<lighthouse-node>/eth/v2/validator/aggregate_attestation?slot=3613623&attestation_data_root=0x25cf9b33dbb83a06ee303595348e984d2bcda2dca31658cb3d8632fed339ffbe&committee_index=32"

Example response:

{
  "code": 404,
  "message": "NOT_FOUND: no matching aggregate found",
  "stacktraces": []
}
