Console log is full of errors (ver 0.10.0)

[joshuao3]

My console keeps registering this error with some requests:

{"level":50,
"time":1701183084869,
"pid":3920,
"hostname":"SERVER",

"v":1}

My install is super vanilla:

var redbirdProxy = require('redbird')({
    host: config.privateIP
  , port: config.privatePort
  , xfwd: false
  , ssl: {
      http2: true,
      key: '..\\ssl\\ssl-drttix.pem',
      cert: '..\\ssl\\ssl-drttix.pem',    
      port: config.publicPort, // 443
      host: config.publicIP
  }
});

for (let ep in config.endpointsRedbird) {
  var endpoint = config.endpointsRedbird[ep];
  redbirdProxy.register('my.domain.com' + endpoint.path, endpoint.target);
}

The proxy is working... I'm getting the expected results in the browser. But the console log is filling up with the error.

When the proxy starts, there is also this error in the log:

(node:4688) [DEP0111] DeprecationWarning: Access to process.binding('http_parser') is deprecated.

Help understanding what's going on would certainly be appreciated. Thanks in advance!
