Retrieving data from a server via an https link

Hello,

I would like to know how to retrieve data from a server and send it to Node-Red. I previously tested the URL on Postman, to see the data sent:

In order to get the correct values ​​I had to add headers.

I would like to retrieve the values ​​in this same form but on Node-Red

I have previously tested something, like this helper:
https://cookbook.nodered.org/http/set-request-header

Doing it on Node-Red gave me this:

Code located in the function block.

Https block :

Recuperation_donne_https_GET

Result obtained, I do not know how to interpret.

Thank you for your answers.
