Línea de trabajo

Comienza en common/lib/utils/monitoring/monitor_service.ts, especialmente en MonitorServiceImpl.checkMonitors(), e inspecciona la ruta de cleanup a través de runCleanupLoop(). Revisa las llamadas a JSON.stringify() utilizadas para el registro de Monitor, incluida la línea referenciada y casos similares. Se considera terminado cuando la actividad de monitorización ya no provoca TypeErrors de serialización de BigInt.

Describe the bug

After upgrading to 3.0.0, I've started to see uncaught exceptions from within the library for TypeError: Do not know how to serialize a BigInt. It appears that MonitorServiceImpl::checkMonitors() attempts to serialize Monitor objects for logging with JSON.stringify(), but these include BigInt members that fail. One such place is:

https://github.com/aws/aws-advanced-nodejs-wrapper/blob/c0a7320e282453a1f023a6d95466d93078d2134d/common/lib/utils/monitoring/monitor_service.ts#L211

There appear to be several other similar cases throughout monitor_service.ts.

Expected Behavior

No exceptions attempting to serialize BigInt.

What plugins are used? What other connection properties were set?

Current Behavior

Example stack trace:

TypeError: Do not know how to serialize a BigInt
at JSON.stringify ()
at MonitorServiceImpl.checkMonitors (file:///redacted/node_modules/aws-advanced-nodejs-wrapper/dist/common/lib/utils/monitoring/monitor_service.js:148:81)
at MonitorServiceImpl.runCleanupLoop (file:///redacted/node_modules/aws-advanced-nodejs-wrapper/dist/common/lib/utils/monitoring/monitor_service.js:106:18)
} reason: TypeError: Do not know how to serialize a BigInt
at JSON.stringify ()
at MonitorServiceImpl.checkMonitors (file:///redacted/node_modules/aws-advanced-nodejs-wrapper/dist/common/lib/utils/monitoring/monitor_service.js:148:81)
at MonitorServiceImpl.runCleanupLoop (file:///redacted/node_modules/aws-advanced-nodejs-wrapper/dist/common/lib/utils/monitoring/monitor_service.js:106:18)

Reproduction Steps

I don't have a quick reproducer since the issue seems to depend on the the monitoring state and activity. In my application, this sometimes happen after some period of inactivity or just before/after activity. I believe attempting to JSON.stringify() a BigInt is always an error unless the library were to provide a replacer function to JSON.stringify().

Possible Solution

Provide a replacer function to JSON.stringify() to handle the BigInt fields or perform some alternative serialization of the Monitor objects for logging.

Additional Information/Context

This is my first bug report here. Thanks for the great library.
