sn_auth.GlideJWTAPI() is adding additional JSON values other than specified

[Brad59]

I have a JWT Provider and I am generating JWT tokens using the GlideJWTAPI. The tokens generate fine but I only have one JSON value in my header variable but the generateJWT function adds an additional value. This value breaks authentication because the vendor server does not accept this value in the header.

var jwtAPI = new sn_auth.GlideJWTAPI();
var headerJSON = {"alg":"RS256"};
var header = JSON.stringify(headerJSON);

//...
//...

var jwt = jwtAPI.generateJWT(jwtProviderSysId, header, payload);

The base64 value that is generated by the generateJWT function is:

{"alg":"RS256","typ":"JWT"}

EDIT
Additionally, the payload value has a jti value added that I did not include:

{
	"aud": "<url>",
	"scope": "<string>",
	"iss": "<issValue>",
	"exp": 1643747002,
	"iat": 1643746942,
	"jti": "1c6683b9-3a47-4809-a5ec-5320c48a7b65"
}

Did you get any help from ServiceNow on this? I'm seeing 'kid' added to the header section which breaks my authentication.
