SLS Migration to 1.16 Version

I am currently on 1.11 version and when I update to latest version 1.16, upload fails and when I switch back to 1.11 version and deploy works.

What changes should I be making to ensure I can use 1.16 version?

Here is the log from ssl deploy with 1.16 version. I tried 1.15 few weeks ago and experienced similar issue.

bash-3.2$ time sls deploy -v -s gali
