This is the error message: Server listening on port xxxx... Error status: 403 Error data: { developerMessage: 'The client_id specified does not have access to the api product', moreInfo: 'https://forge.autodesk.com/en/docs/oauth/v2/developers_guide/error_handling/', errorCode: 'AUTH-001' } Error headers: Object [AxiosHeaders] { server: 'nginx', date: 'Thu, 11 Jul 2024 07:42:33 GMT', 'content-type': 'application/json', 'content-length': '204', connection: 'keep-alive', 'strict-transport-security': 'max-age=31536000; includeSubDomains; preload', 'x-frame-options': 'SAMEORIGIN', 'x-request-id': '78878a7b-a69f-4c68-9811-721e97d73998' }
