Electra /eth/v2/validator/aggregate_attestation returning incorrect response

[Bez625]

When testing on devnet 6 we have been seeing an incorrect API response from /eth/v2/validator/aggregate_attestation. As per the spec we should be receiving the fork version in the response.

I double checked and we do not get the version key in the body or the Eth-Consensus-Version header in the response.

Lighthouse version:

Lighthouse v6.0.1-2193f6a
BLS library: blst
BLS hardware acceleration: true
SHA256 hardware acceleration: true
Allocator: jemalloc (4K)
Profile: release
Specs: mainnet (true), minimal (false), gnosis (false)

Example call:

curl --header "Content-Type: application/json" --header "Accept: application/json"  --request GET --data '' "http://<lighthouse-node>/eth/v2/validator/aggregate_attestation?slot=12122&attestation_data_root=0x9b00809cfb8251fe3e6f41c9a6d12f0d9e876703c5ecc806177623308562af5e&committee_index=3"

Example response:
