Mac L 80359d8ddb Fix attestation performance API InvalidValidatorIndex error (#3503) ... ## Issue Addressed When requesting an index which is not active during `start_epoch`, Lighthouse returns: ``` curl "http://localhost:5052/lighthouse/analysis/attestation_performance/999999999?start_epoch=100000&end_epoch=100000" ``` ```json { "code": 500, "message": "INTERNAL_SERVER_ERROR: ParticipationCache(InvalidValidatorIndex(999999999))", "stacktraces": [] } ``` This error occurs even when the index in question becomes active before `end_epoch` which is undesirable as it can prevent larger queries from completing. ## Proposed Changes In the event the index is out-of-bounds (has not yet been activated), simply return all fields as `false`: ``` -> curl "http://localhost:5052/lighthouse/analysis/attestation_performance/999999999?start_epoch=100000&end_epoch=100000" ``` ```json [ { "index": 999999999, "epochs": { "100000": { "active": false, "head": false, "target": false, "source": false } } } ] ``` By doing this, we cover the case where a validator becomes active sometime between `start_epoch` and `end_epoch`. ## Additional Info Note that this error only occurs for epochs after the Altair hard fork.		2022-09-05 04:50:45 +00:00
