I try to parse a 300 page pdf and get the following content: XXXXXX ----------------Page (0) Break----------------

----------------Page (1) Break----------------

----------------Page (2) Break----------------

----------------Page (3) Break----------------

This is my code：

import PDFParser from "pdf2json";

const pdfParser = new PDFParser(this, 1);

function readPDF(fileName) {
    pdfParser.loadPDF(fileName);
    pdfParser.on("pdfParser_dataError", errData => console.error(errData.parserError));

    pdfParser.on("pdfParser_dataReady", pdfData => {
        const data = pdfParser.getRawTextContent()
        console.log('文本信息:', JSON.stringify(data)
    });
}
readPDF('1.pdf')
