1 year ago @rohits-splunk thanks for reporting! The reason here is likely because the older MongDB NodeJS driver version is not compatible with the version of MongoDB installed. See my comment https://github.com/font/k8s-example-apps/issues/9#issuecomment-1299347902 for more details.
I have installed the app on a bare metal EC2 as docker was not working correctly, My ultimate aim is to send data to an external observability tool through open telemetry , i have also installed the tracing libraries and running the app like this š npm start -- @splunk/otel/instrument
