_My question_:

Newman calls are getting failed for the postman calls which has a token in the request header. Postman request with Token in request is giving response with warning for self signed certificates in postman. Here the postman is able to finish the test whereas Newman scripts are erroring(failing) out.

Reports  
Error: self signed certificate in certificate chain

Roles is full access account undefined

call newman run %CollectionFile% -e %EnvFile% -g %GolbalFile% -r cli, json --folder=Tok2
