The sysvar documentation gives the address of the Epoch Rewards account as
getAccountInfo, I'm getting
"value": null for this address on testnet, devnet, mainnet-beta and a local test validator
The address is found in the
solana-labs/solana source code so I think it's correct in the docs: https://github.com/solana-labs/solana/blob/4385ed11b1a955642944a6b11353c09b1fba9187/sdk/program/src/sysvar/epoch_rewards.rs#L135
It's not marked deprecated in
parse_sysvar where some others are:
Should I just assume it's deprecated and no longer exists on any network?
