Older transactions missing from Get Staking History API

Hello,

I’ve been trying to query the new Staking History API endpoints though it seems that older data is not available when using INTEREST transaction type.

I was able to find 4 months-old locked staking history transactions when exporting data to (XLS files), however querying the API returns an empty list for that period.

//Endpoint params
{"product": "STAKING", "txnType": "SUBSCRIPTION", "startTime": 1643680367000, "endTime": 1647911523000}

//Response
[
    {
        "positionId": 41364471,
        "time": 1645418868000,
        "asset": "SHIB",
        "amount": "1998127.87",
        "lockPeriod": 10,
        "type": "NORMAL",
        "status": "SUCCESS"
    }
]

//Endpoint params
{"product": "STAKING", "txnType": "INTEREST", "startTime": 1643680367000, "endTime": 1647911523000}

//Response
[]

//Endpoint params
{"product": "STAKING", "txnType": "REDEMPTION", "startTime": 1643680367000, "endTime": 1647911523000}

//Response
[
    {
        "positionId": 41364471,
        "time": 1646354696000,
        "asset": "SHIB",
        "amount": "1998127.87",
        "deliverDate": 1646438400000,
        "status": "PAID"
    }
]

I have also ensured that the difference between startTime and endTime is shorter than 3 months, as defined in the API documentation. Though there are no informations about limited history data.

Would it be possible to have all history through the API?

Thank you.

thanks for feedback, we will investigate.
