chiaAgent Dies Trying to Log SSL Error

[stonemelody]

When attempting to send an RPC to a remote machine, the system will die trying to log a TLS verification error (bug for TLS error in #20), showing:

TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'Object'
    --- property 'issuerCertificate' closes the circle
    at JSON.stringify (<anonymous>)
    at ClientRequest.<anonymous> (/Monitor_Project/ChiaMonitorApi/node_modules/chia-agent/rpc/index.js:228:53)
    at ClientRequest.emit (node:events:390:28)
    at TLSSocket.socketErrorListener (node:_http_client:447:9)
    at TLSSocket.emit (node:events:390:28)
    at emitErrorNT (node:internal/streams/destroy:164:8)
    at emitErrorCloseNT (node:internal/streams/destroy:129:3)
    at processTicksAndRejections (node:internal/process/task_queues:83:21)

In this case, printing just the error itself is sufficient to see the real TLS error that was supposed to be printed
