A short description of the issue: Error when trying to get any form of color from chart.getOptions().get(anything with color)

A small code sample that reliably reproduces the issue. The sample should run as-is or with minimal setup, without external dependencies.

function myFunction() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var chart = sheet.getCharts()[0];
  var chartOptions = chart.getOptions();
  var chartTitle = chartOptions.getOrDefault("backgroundColor")
  console.log(chartTitle)
}

What is the expected output? What do you see instead? If you see error messages, please provide them. The expected output is the color of the option e.g legend.textStyle.color but the error shows Exception: Unexpected error while getting the method or property getOrDefault on object Charts.ChartOptions. myFunctionCode.gs:5
