   broker can not launch successfully, it's log

   It means some datasources the device_id_sketch is null, so I check my 
datasource and ingestion spec

   this is my ingestion spec about metricsSpec
   ```
   "metricsSpec": [
         {
           "type": "longSum",
           "name": "behavior_total_times",
           "fieldName": "behavior_total_times",
           "expression": null
         },
         {
           "type": "thetaSketch",
           "name": "device_id_sketch",
           "fieldName": "device_id",
           "size": 16384,
           "shouldFinalize": true,
           "isInputThetaSketch": false,
           "errorBoundsStdDev": null
         }
       ]
   ```
   
   So why my device_id is not null, but device_id_sketch is null,and why 0.20.2 
it run well,but upgrate 24.0,it fails
