我正在尝试从lamda运行gumCrawler，但我得到

2019-11-07 13:23:12 [main] ERROR com.zuzu.historicalbookings.service.TransformationService:44 - com.amazonaws.services.glue.model.AWSGlueException: null (Service: AWSGlue; Status Code: 500; Error Code: InternalFailure; Request ID: bf7dce73-0161-11ea-9780-091548e0b38e)

我认为也许AWSGlueAsync为null，但是当我尝试登录时也不为null。 我正在使用以下代码来启动搜寻器

   AWSGlueAsync awsGlueclient= AWSGlueAsyncClient.asyncBuilder().withRegion("us-east-1").build();
        StartCrawlerRequest startCrawlerRequest=new StartCrawlerRequest();
        startCrawlerRequest.setName(applicationProperties.getHistoricalCSVCrawler());
        LOGGER.info("###Glue##"+awsGlueclient);
        LOGGER.info("###########Started Crawler###################");
        awsGlueclient.startCrawler(new StartCrawlerRequest());

下面是stacktrace：
