Attestation Rewards API endpoint broken on Pectra enabled networks

[peterbitfly]

When executing the following API call against a lighthouse node running on pectra-devnet-5 (docker.ethquokkaops.io/dh/ethpandaops/lighthouse:single_attestation-b6d80eb) we get the following error:

curl -X POST --data '[]' http://localhost:4000/eth/v1/beacon/rewards/attestations/826

{"code":500,"message":"INTERNAL_SERVER_ERROR: unexpected error: AttestationRewardsError","stacktraces":[]}

at the same time we see the following error in the ligthouse log:

lighthouse-1  | Jan 20 06:48:37.419 WARN Error processing HTTP API request       method: POST, path: /eth/v1/beacon/rewards/attestations/826, status: 500 Internal Server Error, elapsed: 84.008069ms

The requests works up until devnet-5 epoch 302. For later epoch all requests fail:

curl -X POST --data '[]' http://localhost:4000/eth/v1/beacon/rewards/attestations/302 --> works
curl -X POST --data '[]' http://localhost:4000/eth/v1/beacon/rewards/attestations/303 --> fails

I assume the endpoint fails once a validator has an effective balance > 32 ETH.

Nice catch, thanks!

Looks like you're exactly right and we need to update the maximum effective balance for which we calculate ideal_rewards.

I'll have a quick go at this now.

Fixed by:

• Update attestation rewards API for Electra #6819

Part of unstable now and will be in the v7.0.0-beta.0 release.
