Extract text is not wotking

[vats147]

I am working with PDF where I need to extract text but, any of text extracting method is not working.

const { PDFDocument } = require('pdf-lib');
const fs = require('fs');

async function removetext(inputPath, pageNumber) {
  // Read the input PDF file
  const pdfDoc = await PDFDocument.load(fs.readFileSync(inputPath));

  // Get the page that you want to extract text from
  const page = pdfDoc.getPage(pageNumber);

  // Get the text content of the page
  const textStream = page.getTextContent();

  // Get the text as a string
  const text = textStream.getText();

  return text;
}

// Call the extractText function to extract text from page 1 of the input.pdf file
const text = removetext('fileupload.pdf', 1);

// Print the extracted text to the console
console.log(text);

error : TypeError: page.getTextContent is not a function
TypeError: page.extractText is not a function

is there any replacement in of function in new realse??
