api I got error:
       my code :
       this line work fine :
       ResponseEntity<String> b = restTemplate.getForEntity("http://"; + 
serverIp + "/kylin/api/model/{modelName}", String.class, "kylin_sales_model");
       
       this line got error:
       ResponseEntity<String> a = restTemplate.getForEntity("http://"; + 
serverIp + "/kylin/api/tables/{tableName}", String.class, "KYLIN_SALES");

       error from kylin.log:
