Network>Staking>Payout Displays Claimed Eras as Unpaid

[ayushmishra2005]

I'm submitting a Bug report.

After upgrading Cere Network chain to Polkadot v1.4.0, validators have reported a peculiar issue related to payouts:
Validator Issue Description:

• The validator still shows up as needing to be paid out in the payouts section.

• When we manually trigger the payout using staking.payoutStakers, it throws the error AlreadyClaimed.

• On the targets tab, the validator does not appear under recently claimed.

Current vs. Expected Behavior

Current Behaviour:

• The validator still shows up as needing to be paid out in the payouts section.

• When we manually trigger the payout using staking.payoutStakers, it throws the error AlreadyClaimed.

• On the targets tab, the validator does not appear under recently claimed.

Expected Behaviour:

•	Paid validators should not appear in the payouts section.
•	They should be listed under the recently claimed section in Staking >> Targets.

Observation:
I tested this issue for a specific validator and era. Here are the details:

Validator Name: Dynasty
Account ID: 6V5smKXq1YBpKNdxNKGMryDvefVPQ1rF2GErXrBMZdEWfQ3E
Era: 1263

Steps and Observations:

1. Checked the validator’s free balance before triggering the payout:
   Free Balance (Before): 823,654,656,248,945.
2. Manually triggered staking.payoutStakers for Era 1263.
3. Checked the validator’s free balance again after the payout:
   Free Balance (After): 830,819,368,310,623.

The difference:
830,819,368,310,623 - 823,654,656,248,945 = 7,164,712,061,678

This translates to 716.4712061678 CERE paid out as a reward for the era, which is correct. I have screenshots for the same.

The difference matched the expected reward amount, confirming that the payout was processed successfully on-chain.

Steps Taken So Far:

1. Verified reward points and staking details for the validator.
   • Validator actively participated in the specified era, with reward points and stake details consistent with expectations.
2. Checked for pending payouts:
   • Validator is still showing as needing a payout.

This issue began immediately after upgrading to Polkadot v1.4.0. I suspect it may be related to changes introduced in this PR to make legacy staking compatible with v1.4.

I suspect this might be related to a UI-related issue with PolkadotJS Apps.
