why i am getting HTTP status 401- Unauthorized??

[Manikantahere]

When I tried with Rest message test connection it is giving me 200 but when I am doing through below script it is throwing me 401? can any one help me in solving out this?

 var body = {"ApproverName":inputs.approver,"UniqueID" : inputs.approvalSysid,"ApproverMail":inputs.approverMail,"RequestItem" :inputs.requestItem,"RequestItemSysId":inputs.itemSysId,"RequestItemName":inputs.title,

  "RequestorMail": inputs.requestorMail,"RequestorName" : inputs.requestorName, "ApprovalType" : "Sequential", "ApplicationName" : "ServiceNow"} ;

  var abc = JSON.stringify(body);

gs.log('test1 - '+abc);

var tokenvalue = gs.getProperty("powerAutomate_request_token");

gs.log("token value is "+tokenvalue);

try{

var power_request = new sn_ws.RESTMessageV2();

power_request.setHttpMethod("post");

power_request.setEndpoint("3rd party end point");

power_request.setRequestHeader("Authorization", "Bearer " +tokenvalue);

power_request.setRequestHeader("Accept","application/json");

power_request.setRequestHeader("Content-Type","application/json");

power_request.setRequestBody(abc);

var response = power_request.execute();

var xyz = power_request.getRequestBody();

var httpstatus = response.getStatusCode();

gs.log('ResponseBody - '+xyz);

gs.log("test 4 "+httpstatus);

}

catch(ex){

    var message = ex.message;

    gs.log("test6 "+message);

}
