Q:

NetSuite - Returning an header is not NLAuth scheme error , when I am using OAuth

I am trying to call a Restlet from a User Event Script which returns Customer information using Token Based Authentication . 
But I receive an user error which says header is not NLAuth scheme
I know this means that I have to use the NLAuth scheme , but why is it giving this error?
Here is the authorization header I am using
 var headers =  { 'Authorization': 'Oauth realm="XXXXX", oauth_consumer_key="XXXXX" , oauth_token="XXXXX", oauth_nonce="XXX",oauth_timestamp="XXXX", oauth_signature_method="HMAC-SHA1", oauth_version="1.0",oauth_signature="XXXXXXXXXX="',
                'content-type': 'application/json'
                };

A:

You need to capitalize the "a" in "Oauth"
Oauth -> OAuth

A:

Make sure that you are using the account ID for the realm and that it is formatted correctly. 12345_SB1 
The underscore must be used if that applies to your account
The letters must be capitalized.
