monero-wallet-roc throws an exception when certain rpc requests get made from the pool but doesn't when sent via curl

First of all thank you for your work.

I'm currently setting up the pool software, running monero-wallet-rpc with the following command:

monero-wallet-rpc --config-file /path/to/config.conf This is my config file:

daemon-address=127.0.0.1:18081
rpc-bind-port=18085
rpc-bind-ip=127.0.0.1
wallet-file=/path/to/wallet
password=<redacted>
log-level=0
log-file=/var/log/mwrpc.log
disable-rpc-login=1

After a while I get the following error in the session running monero-wallet-rpc:

2022-08-03 02:59:47.804E !r. THROW EXCEPTION: tools::error::no_connection_to_daemon
2022-08-03 02:59:47.804E Exception at while refreshing, what=no connection to daemon

I looked at netstat - napt which showed the connection as ESTABLISHED. I then monitored the traffic with tshark in another window and saw that the connection error occurs at the point a JSON rpc request gets made. But when I send a request via curl, i.e. get_height:

curl http://127.0.0.1:18085/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_height"}' -H 'Content-Type: application/json'

I get the correct output of the current height, which means it has to have a connection to the daemon:

{
  "id": "0",
  "jsonrpc": "2.0",
  "result": {
    "height": 2681215
  }

Can I ignore the errors that are thrown, as there are no errors in the pool logs I see while the error occurs in monero-wallet-rpc and it looks like the pool gets the correct values from the rpc request?

The error/exception is coming from the monero-wallet-rpc, not the pool. If you want to report an issue with the monero-wallet-rpc then you need to do so on that repository.

I have actually already created one: https://github.com/monero-project/monero/issues/8477

Is there any way I can check if the pool withdrawals work correctly, as that is my main concern? Can I manually set the current due balance of a user so I can try withdrawing XMR?

Just mine to testnet if you're worried.
