Nodeshift - unable to verify the first certificate

I am middle of a deployment Angular application by nodeshift, but I am struggling with the following error unable to verify the first certificate that appears when I run this regular command: nodeshift --strictSSL=false --dockerImage=bucharestgold/centos7-s2i-web-app --imageTag=10.x --build.env OUTPUT_DIR=dist/angular-web-app. Basically, I have a configured proxy by my corporate, so npm works fine, but I don't know if there is missing something during the usage of nodeshift. I will be grateful for indicating the solution.
