This is due to one of the changes mentioned in this PR :

StakingLedger.claimed_rewards, renamed to StakingLedger.legacy_claimed_rewards.

The reason of the renaming is because the use of StakingLedger.legacy_claimed_rewards is being deprecated and will be removed.

This directly impacts Sidecar's staking-info endpoint where all information found in StakingLedger is returned without any validation on specific fields, as seen here. Hence, as soon as the last runtime upgrade (v1.2.0) was enacted and the change took effect :

• on Kusama (era 6514 (Apr 18)) and
• Polkadot (era 1420 (Apr 21))
  (eras and dates mentioned in this PR)

it also resulted in the renaming of the field in Sidecar's response.

I will check the code in detail tomorrow and keep you updated of any related fixes.
