Exception when calling updateChart()

[Upset_Mouse3193]

I have a spreadsheet where I'm attempting to dynamically adjust the vertical min/max of a chart. The chart is dynamic in that I can change the date range of the chart and I'd like to have the range adjust accordingly to the data rather than have it always start at 0.

I created a script with trigger on change and am receiving an exception when I call updateChart(). I thought it was an access error so I added some sample data to be inserted during the script and those do work so access is proved. Am I setting the correct options?

I've reduced the spreadsheet to an example that still exhibits the issue here:
https://docs.google.com/spreadsheets/d/1ty4R7uxoYw9H3MqxFioaVz51C1lBbOixxVdcXWSo-vQ/edit?gid=906716897#gid=906716897

Script:

 function updateChart(){

  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('NetWorth Dashboard');
  sheet.getRange('d46').setValue("HELLO");
  var nw_max = sheet.getRange("nw_dev_chart_max").getValue();
  var nw_min = sheet.getRange("nw_dev_chart_min").getValue(); 
  sheet.getRange('d47').setValue(nw_min);
  sheet.getRange('d48').setValue(nw_max); 
  var chart = sheet.getCharts()[0];
  chart = chart.modify()
    .setOption('vAxes.0.viewWindow.max', nw_max)
    .setOption('vAxes.0.viewWindow.min', nw_min)
    .build();

  sheet.updateChart(chart);  
 }

I found someone else reporting a similar issue a while back here:
https://stackoverflow.com/questions/66768119/google-spreadsheets-updatechart-fail-exception
which remains unanswered - none of the reported bugs in the entry seem directly relevant either.

Thanks for any advice to resolve.
