在使用elasticsearch脚本指标统计时，出现了异常：
脚本：

POST account_test/_search?size=0
{
   
  "query": {
   
    "match_all": {
   }
  },
  "aggs": {
   
    "balance_positive_sum": {
   
      "scripted_metric": {
   
        "init_script": "state.balances=[]",
        "map_script": "if(doc.balance > 0){state.balances.add( doc.balance)}",
        "combine_script": "double balanceSum=0;for(num in state.balances){balanceSum+=num} return balanceSum ",
        "reduce_script": "double balanceSum=0;for(num in states){balanceSum+=num} return balanceSum"
