Failed to get the current sub/segment from the context and addAnnotation of NULL issue in NodeJS

I am getting "Failed to get the current sub/segment from the context" with node lambda. AFter adding environment variable as suggested in another post, I am getting addAnnotation of NULL. Because of this my test are getting failed.

Is there any workaround to make this pass? Help is much appreciated.

Which other post are you referring to? Can you post the code to reproduce?

When in Lambda, X-Ray does not have access to the segment. The segment is created by Lambda and sent independently. In order for the X-Ray service to reconstruct the full segment/subsegment structure, the SDK picks up an environment varibale set by Lambda, and creates a "facade segment". This represents a placeholder to build off of and cannot be modified.

Typically we advise to create a new subsegment and add the annotation there. Keep in mind, this will only work within the handler.
