How to solve error code "InvalidAuthenticationToken"

Problem

The following error message may appear when we execute an HTTP request:

Error : 
 
{
    "error": {
        "code": "InvalidAuthenticationToken",
        "message": "CompactToken parsing failed with error code: 80049217",
        "innerError": {
            "date": "2022-09-16T08:36:52",
            "request-id": "cc17d770-f93d-40b6-8643-6c0d1534c644",
            "client-request-id": "cc17d770-f93d-40b6-8643-6c0d1534c644"
        }
    }
}

Solution

In most cases, the problem is caused by the wrong Authorization key value, i.e., Bearer{{AccessToken}} instead of Bearer {{AccessToken}}, with a space between the word Bearer and the Access Token.
