AWS X-Ray: how to propagate TraceId through Lambda --> SNS --> Lambda?

Question

I have the following architecture:

API Gateway --> Lambda 1 --> SNS 1 --> Lambda 2 --> SNS 2 --> Lambda 3 (an Scatter-Gather pattern).

The TraceId is generated in API Gateway and propagated successfully to Lambda 1. My question is: how to pass that TraceId through SNS in order to reach Lambda 2? (propagating the TraceId through SNS 2 should be trivial once I've done this).

Lambda 1 is a .NET Core WEB API backend, and Lambda 2 and 3 are normal Lambdas listening for SNS messages

Unfortunately there is no workaround to continue the trace context from SNS to the triggered lambda2 or further workflow as you have described right now. This requires a change on SNS side to put the trace context when it invokes the target lambda function. We are already aware of this feature request and we are looking into a plan with SNS and Lambda team to provide better customer experience. Please stay tuned.
