getTextDimensions expects text-parameter to be of type String or type Number or an Array of Strings.

I’m using Typescript in a React project and I follow the example for creating a table on the Live Demo site but I get the following error: getTextDimensions expects text-parameter to be of type String or type Number or an Array of Strings.

I check the type of the arguments for .table() and the headers argument is string[] which is unexpected because the demo is using object[]. I change to the type asked for by the argument but I still get the same error.

Below is an MCVE in node:

const { jsPDF } = require('jspdf')

function test() {
  const test = new jsPDF('landscape')
  const headers = [
    'Name',
    'Student_Date_Of_Birth',
    'Student_ID_No_Course',
    'Course',
    'Course_Total_Tuition_Fee',
    'Course_Intake',
    'Course_Year',
    'Course_Start_Month',
    'Commission_Rate',
    'Commission_Payable'
  ]
  const invoiceObjectTableRows = [
    {
      Name: 'testing',
      Student_Date_Of_Birth: 'testing',
      Student_ID_No_Course: 'testing',
      Course: 'testing',
      Course_Total_Tuition_Fee: 'testing',
      Course_Intake: 'testing',
      Course_Year: 'testing',
      Course_Start_Month: 'testing',
      Commission_Rate: 'testing',
      Commission_Payabl: 'testing'
    }
  ]
  test.table(5, 105, invoiceObjectTableRows, headers, { autoSize: true })
}
