我正在使用 here.com api 来计算美国乔治亚州劳伦斯维尔和洛克伯恩博士的两个位置之间的距离，请参阅下面的网址
https://route.ls.hereapi.com/routing/7.2/calculateroute.json?apiKey=API_KEY&waypoint0=geo!33.95312,-83.98804&waypoint1=geo!39.26732,-84.54907&routeattributes=wp,sm,sh,sc&mode=fastest;truck。但它给了我 400 bad reqest 的错误。我收到以下回复。
{"_type":"ns2:RoutingServiceErrorType","type":"ApplicationError","subtype":"NoRouteFound","details":"Error is NGEO_ERROR_GRAPH_DISCONNECTED","additionalData":[{"key":"error_code","value":"NGEO_ERROR_GRAPH_DISCONNECTED"}],"metaInfo":{"timestamp":"2021-04-06T17:35:53Z","mapVersion":"8.30.119.151","moduleVersion":"7.2.202114-8610","interfaceVersion":"2.6.76","availableMapVersion":["8.30.119.151"]}}
请帮帮我。
