1. Created the External Named credential with name Samsung Test enter image description here

  2. Added the Principal enter image description here

  3. Added the permission set enter image description here

However I am not able to fetch this named credential in Apex code.

HttpRequest req = new HttpRequest();
Http http = new Http();
HTTPResponse res = http.send(req);

System.CalloutException: The callout couldn't access the endpoint. You might not have the required permissions, or the named credential "samsungtest" might not exist.

You have named your Named Credential "samsungtest" but in the Apex you are calling out to samsungtest2.

    My bad. I edited it. It was my mistake. The problem is the same.
