BP-01-001 Delete API Key Delay

[yanping891003]

I can call it normally for a few minutes after deleting the API Key. After a few minutes it returns {"error":{"code":-32000, "message": "record not found"}}.
url:http://klaytn.testnet.blockpi.net/v1/rpc/9e63be8ecce16f51ab6c6bbdbab47f59b6e1f913

The following return has occurred during the call:
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"klay_blockNumber","params":[],"id":83}' http://klaytn.testnet.blockpi.net/v1/rpc/9e63be8ecce16f51ab6c6bbdbab47f59b6e1f913
{"jsonrpc":"2.0","id":83,"error":{"code":-32000,"message":"the header does not exist (block number: 94166330)"},"result":"0x59cddb0"}

Does this occur to indicate a problem?

Confirmed the same API key delete delay.

Deleted API key off of the dashboard. Could still send requests for ~3-5 minutes after deletion. Eventually see:

{
  "error": {
    "code": -32000,
    "message": "record not found"
  }
}
