Important: in addition to using the plugin, you need to enable capturing traces in the code as well:
const awsXRay = require('aws-xray-sdk'); const awsSdk = awsXRay.captureAWS(require('aws-sdk'));
The plugin only controls the checkbox that be viewed in AWS Console:
go to AWS Lambda -> select a Lambda function -> Configuration tab -> Advanced settings ->
"Enable active tracing". If
tracing ends up being
true for a function,
the checkbox will be checked for that function.
