I upgraded my SDK to 3.2.0, my CB server is 6.6. In my dev env I could not reproduce the crash.
However, on the production env (CB server is also 6.6), which is hosted in AWS with containers, the application became stuck in crash loop, with the dump as below:

Is CB server 7.0 required for running node.js SDK 3.2.0?
