5 months ago Hey @bhaskarbanerjee
Do you see any debug logs from the sdk you should see a lot with the OTEL_LOG_LEVEL set to "debug"
just fyi the log level needs to be all lower case.
You can find the code for the tracer here https://github.com/baselime/node-opentelemetry/blob/main/src/baselime.ts

5 months ago It doesn't look like you are creating any spans.
I'd recommend installing our node-opentelemetry package and using the withOpentelemetry middleware for lambda from it to trace your lambda function

5 months ago I am trying a simple hello world app. Do I need to explicitly create spans?
`'use strict';
exports.handler = async (event) => {
console.log("Hello World") return { statusCode: 200, body: JSON.stringify('Hello from Lambda!!'), }; };`

5 months ago Doesn't the layer work out of the box i.e. adding the layer and setting ENV VARs? Or is a code change in the lambda MUST to invoke/utilize this layer?

5 months ago @Ankcorn similar to https://baselime.io/docs/sending-data/lambda-extension/

5 months ago You need to change the code.
Would look something like this
const { withOpentelemetry } = require('@baselime/node-opentelemetry/lambda');
exports.handler = withOpentelemetry((event) => {
return {
statusCode: 200,
body: JSON.stringify('Hello from Lambda!!'),
};
});If you are using the tag system and are signed up to baselime you can do it without code changes but otherwise you need to import the middleware

5 months ago OK, Tried but it ended in an error. Have removed the layer too.

5 months ago @Ankcorn slight change to the code but now a different error
`const { baselime } = require('@baselime/node-opentelemetry');
exports.handler = baselime.withOpentelemetry((event) => { return { statusCode: 200, body: JSON.stringify('Hello from Lambda!!'), }; }); `
{
"errorType": "TypeError",
"errorMessage": "Cannot read properties of undefined (reading 'withOpentelemetry')",
"trace": [
"TypeError: Cannot read properties of undefined (reading 'withOpentelemetry')",
" at Object.
Any suggestions?
Question - I am trying to use this opensource and send data to another collector. I am assuming that does not require the prerequisite of connecting my aws account with Baselime. I have built the layer using scripts/publish.sh and created a layer out of that. I have attached the layer to my lambda and am setting up the following ENV vars
AWS_LAMBDA_EXEC_WRAPPER /opt/baselime BASELIME_ACTUAL_HANDLER app.handler BASELIME_API_KEY 0123456789 (a ficticious key) COLLECTOR_URL my_collector_url:port OTEL_LOG_LEVEL DEBUG
My lamnbda's logs show no errors but the collectior doesn't receive any data either. Additionally, I do not see any console out from this layer. Seeking your suggestions on how to proceed with this.
My lambda handler is also set to app.handler.
