Hello! I cannot reproduce this. Could you please provide precise step by step reproduction, as well as the logs from the time of the crash, the source of the minimal sql file that reproduces the issue, the exact database version, and the database schema and data if relevant?

[lovasoa]

the exact version of the odbc driver would also help reproducing the issue

the sql is:

select 
    'echarts/bar'             as component,
    $examname||'stat' as title,
    '['||(listagg(''''||year||'''',',') within group (order by year asc))||']' as labels,
    '['||(listagg(''''||cou||'''',',') within group (order by year asc))||']' as cous,
    400 as height,
    to_char(sysdate,'YYYY-MM-DD HH24:MI:SS') as searchtime,
    $examid as examid,
    $examname as examname
from zkbdwh.examstat_info where examid=$examid --and instr((select ),$examid)>0--
order by year desc;

download the echart js package. and create a template such as bar.handlebars
<div id="mainbar" style="width: 100%;height:{{height}}px;"></div>
<script type="text/javascript" nonce="{{@csp_nonce}}" src="/static/echarts.min.js"></script>
<script type="text/javascript" nonce="{{@csp_nonce}}">
` var myChart = echarts.init(document.getElementById('mainbar'));

  var option = {
    title: {
      text: '{{{title}}}'  
    },
    tooltip: {},
    legend: {
      data: ['count']
    },
    xAxis: {
      data: {{{labels}}}
    },
    yAxis: {},
    series: [
      {
        name: 'students',
        type: 'bar',
        data: {{{cous}}}
      }
    ]
  };
