'null' value in the authentication Response

[Ramiiyan]

Description:

'null' value is appeared in the authentication response when invoking the API with Authentication header.

API request (curl) :

curl -X GET 'https://localhost:8243/pizzashack/1.0.0/menu' \
--header 'accept: application/json' \
--header 'Authorization: Bearer '

Response :

"errors": [
   {
"code": "900902","details": "Missing Credentials", 
"detail_arguments": "Invalid Credentials. Make sure your API invocation call has a header: 'null : Bearer ACCESS_TOKEN' or 'null : Basic ACCESS_TOKEN' or 'apikey: API_KEY'"
}

Steps to reproduce:

• Published an API via the publisher portal.
• Went to the devportal and tried to invoke the API without parsing an access token. (just an empty value) and we got the below response with a null value for the Authorization header name.

Affected Product Version: 3.2.0
