getRawTextContent() method not consistent in multiple sequential calls

This code parses two pdf files and converts to rawtext and removes the line starting with 'Generated' and then compares those two text files.This method is called more than once sequentially and for each call the arguments to the method changes, but the raw content is not getting replaced for the last call.

function compareGeneratedReportContent(samplePDFFile, sampleXLSXText) {
    const pdfParser = new PDFParser(this, true)
    const pdfParser2 = new PDFParser(this, true)
    const pdfExportPath = path.join(__dirname, '../../resources/report-test/PDFExportedFile.pdf')
    const xlsxExportPath = path.join(__dirname, '../../resources/report-test/XLSXExportedFile.xlsx')
    let content1 = ''
    let content2 = ''
    let result = false

    pdfParser2.on('pdfParser_dataError', errData => console.log(errData))
    pdfParser2.on('pdfParser_dataReady', () => {
        content2 = pdfParser2.getRawTextContent().replace(/^.*(Generated).+$/mg, '')
        // console.log('content2 ', content2)
        fs.writeFileSync(path.join(__dirname, '../../resources/report-test/sample.txt'), content2, 'utf-8')
    })
    pdfParser2.loadPDF(path.join(__dirname, `../../resources/report-test/${samplePDFFile}.pdf`))

    pdfParser.on('pdfParser_dataError', errData => console.log(errData))
    pdfParser.on('pdfParser_dataReady', () => {
        content1 = pdfParser.getRawTextContent().replace(/^.*(Generated).+$/mg, '')
        // console.log('content1 ', content1)
        fs.writeFileSync(path.join(__dirname, '../../resources/report-test/generated.txt'), content2, 'utf-8')
    })
    pdfParser.loadPDF(pdfExportPath)

    let readContent2 = fs.readFileSync(path.join(__dirname, '../../resources/report-test/sample.txt'), 'utf-8')
    let readContent1 = fs.readFileSync(path.join(__dirname, '../../resources/report-test/generated.txt'), 'utf-8')
    if (readContent2 === readContent1) {
        console.log('Report pdf file content matches')
        result = true
    } else {
        console.log('Error in matching contents of report pdf')
        result = false
    }
}

```Can anybody help?

Start at getRawTextContent() and the pdfParser_dataReady handlers in compareGeneratedReportContent, then reproduce the reported behavior with sequential calls using different PDF arguments. Verify that each call returns and writes the raw content for its own input rather than retaining content from an earlier call.
