                               inside "CreateTransactionInsurance copy" of ""     

How you can see, there are two request.
But when I try to use the --ssl-client-cert

The newman test shows only that One request was executed.
After the information table shows "path must be a string" message with no more information.

path must be a string

I really don't know what is happening, I need some help. I'm new using postman api and newman cli.
Thanks, and sorry for create an issue.

@estebancoria Your issue (self signed certificate in chain...) can be resolved by including the -k CLI argument in your newman run command (which will disable SSL certificate validation). The final command would be:

newman run 'collections/mycollection.json' -d 'data/mydata.json' -e 'environments/rc.json' --ssl-client-cert mycert.pem -k

Feel free to get back to us if you're facing difficulties 😄

@kunagpal thanks a lot. And sorry.

@estebancoria No worries. Have fun developing with Postman and Newman!
