Edge Micro verify the installation -Error

[davidvara]

Hello, I would appreciate some help. I want to verify my Edge Micro installation. I would like to know what I am missing, I am following the steps from this page.

https://docs.apigee.com/microgateway/latest/setting-and-configuring-edge-microgateway

So when I run this command

edgemicro verify -o myorg -e dev -k somekey -s somesecret

I have the following error

current nodejs version is v6.13.0
current edgemicro version is 2.5.11
/usr/lib/node_modules/edgemicro/node_modules/microgateway-config/lib/network.js:215
            opts = enableTLS(config, opts);
