Can you please check if the integration user has right set of roles like rest_service,itil etc in order to access the Incident table?

Please let me know after checking.

I am using Admin role user in basic authentication and with same user, its working in postman and same is not working in SharePoint Framework (SPFx).

Note: I am also converting the credential as Base64 and passing to headers as below

var credBase64 = btoa(user + ':' + password);

        const requestHeaders: Headers = new Headers();

        requestHeaders.append('Content-type', 'application/json');

        requestHeaders.append('Accept', 'application/json');

        requestHeaders.append('Access-Control-Allow-Origin', '*');

        requestHeaders.append('Authorization', 'Basic' + credBase64);

const httpClientOptions: IHttpClientOptions = {

          headers: requestHeaders,

          method: 'GET',

          mode: 'no-cors',

        };

this._httpClient

          .get(

            'https://devinstance.service-now.com/api/now/table/incident?',

            HttpClient.configurations.v1,

            httpClientOptions

          )

          .then((response: HttpClientResponse) => {

            debugger;

            console.log('Response Object: ' + response.json());

            return response.json();

          })

          .then((responseJSON: ServiceNowTicketEntity) => {

            debugger;

            console.log('Response Object 1: ' + responseJSON);

            console.log(responseJSON);

            //return responseJSON.title;

            resolve(responseJSON);

          });
