Newman loads the pfx certificate but it is not used to connect to the endpoint - ssl

Question

I'm having issue in execute a postman collection, from newman, which involves loading a pfx certificate to establish a TLSMA connection.
From the Postman application, the certificate is loaded correctly (from the setting) and used for the domain https://domain1.com to connect with a TLSMA counterpart server.
When I export the json collection and environment there is no mention about domain and certificate associated.
Checking the json schema here newman accepts a certificate definition in the request but applying it does not work, here my example:
"request": {
"method": "GET",
"header": [],
"certificate": {
"name": "Dev or Test Server",
"matches": ["https://domain1.com/*"],
"cert": { "src": "./certificate.pfx" }
},
"url": {
"raw": "https://domain1.com/as/authorization.oauth2",
"host": ["https://domain1.com"],
"path": ["as", "authorization.oauth2"],
"query": [
{
I also tried to apply the certificate configuration in an external file cert-list.json with the following content:
[{
"name": "Dev or Test Server",
"matches": ["https://domain1.com/*"],
"cert": { "src": "./certificate-t.pfx" }
}]
but it does not work either.
Here the newman command:
newman run domain.postman_collection.json -n 1 --ssl-client-cert-list cert-list.json -e env.postman_environment.json -r cli --verbose
Do you know where I am doing wrong?

Answer 1

Change cert to pfx
try:
[{
"name": "Dev or Test Server",
"matches": ["https://domain1.com/*"],
"pfx": { "src": "./certificate-t.pfx" }
}]
