[Bug]: Error when calling api "Create store on-chain wallet transaction."

[warrenbdev]

What is your BTCPay version?

BTCPay Server v1.13.0+5b31d4de2

How did you deploy BTCPay Server?

I deployed on Lunanode

What happened?

Error when calling api "Create store on-chain wallet transaction."

Error: Error during POST to https://btcpay.mydomain.com/api/v1/stores/6hEWBQnuK3chzLpWm2yJ1ha8eDRA2Nm5kLrRMgPrizyu/payment-methods/OnChain/BTC/wallet/transactions. Got response (422): [{"path":"Destinations","message":"You are attempting to send more than is available"},{"path":"SelectedInputs","message":"There are no available utxos based on your request"}]
In my destination I have "subtractFromAmount": true
The amount is the total confirmed balance on the wallet
Post body would be like;
{
"destinations": [
{
"destination": "bc1qczmc5uuyvfrjd68cnfydlrraj0su6f2xr70s2g",
"amount": "0.00023266",
"subtractFromAmount": true
}
],
"feeRate": 3
}

How did you encounter this bug?

Testing the api with PHP, this is the only api call that throws an error for me.
I am trying to send the total confirmed balance, but have also tried smaller amounts with the same problem

Relevant log output

What browser do you use?

@pavlenex I discussed with @warrenbdev on Telegram and said this should not happen, that said I tried to reproduce the problem on testnet but was not able to.

Wallet balance confirmed: 0.00007454 BTC

Payload:

{
    "destinations": [
        {
            "destination": "tb1qryux32hzm7y7q0su53f7mgrjstlw6cj8wg2m5j",
            "amount": "0.00007454",
            "subtractFromAmount": true
        }
    ],
    "feeRate": 3
}

Result:

{
    "transactionHash": "db74af29e54f1696d96aa65a2627beb7363ff07ac8689dff15ef00df0e5a9037",
    "comment": "",
    "labels": {},
    "amount": "-0.00007454",
    "blockHash": null,
    "blockHeight": null,
    "confirmations": 0,
    "timestamp": 1712738971,
    "status": "Unconfirmed"
}

@warrenbdev are all inputs confirmed in your wallet balance? As you are onchain, your feerate is below the dust limit, so try to use a competitive feerate.

Thanks @ndeet . All inputs are confirmed yes. I have tried various fee rates from 1 to 50 and I get the same error. Could this be a problem on the mainnet only ?
