Hello Everyone,

I am facing this below error, I am using this library in my RN project i think there are some code which is trying to use the Node.js os module, which is not available in the React Native environment. React Native doesn't support Node.js core modules like os, fs, etc. Is there newer or older version of OpenTelemetry that offers better React Native support.

error: Error: Unable to resolve module os from /Users/praveen36singhq/Desktop/demoCoach/TodoListMobile/node_modules/@opentelemetry/resources/build/src/detectors/platform/node/HostDetectorSync.js: os could not be found within the project or in these directories:

Hi @Moonubanna - could you provide some info on how you are you importing this?
From what I can tell, the metro.config.js should default to resolving whatever is specified in the "browser" field of a package, so I'd assume that this should work fine for resource detectors and you should get a no-op detector instead of the Node.js one.

Are you able to share your metro.config.js?

Also - please note that React Native is not officially supported by this project.
