App is not able to write to the database , nor it is able to query from it

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 👍
npm start -- @splunk/otel/instrument

@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 font/k8s-example-apps#9 (comment) for more details.
