bitcoind – Rpc task queue is overflowing.

Attempting to make an rpc call to the rpc interface “listunspent”. So I get this error: ESOCKETTIMEDOUT. When I checked the Bitcoin node debug file, I saw an error message saying “Depth queue work received”. Added this option rpcworkqueue= setting to bitcoin.conf file.

Here is my bitcoin.conf file

prune=550 port=8333 rpcworkqueue=1000 rpcuser=user rpcpassword=userpass zmqpubrawblock=tcp://127.0.0.1:29000 zmqpubrawtx=tcp://127.0.0.1:29000 zmqpubhashtx=tcp://127.0.0.1:29000 zmqpubhashblock=tcp://127.0.0.1:29000

Below is the error response I get while trying to make an rpc call in my node app.

        "simple": true,

}

Could you help me solve this problem?
