UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'fonts' of undefined

[uclnj]

Testing code using Jest examples, fails on the mock up createPdf function.

(node:19460) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'fonts' of undefined
    at PDFDocument.endAcroForm (C:\code\testpdf\node_modules\pdfkit\js\pdfkit.js:5472:39)

It never gets past the init of createPdf.

`const fs = require('fs') const PDFDocument = require('pdfkit') const signer = require('./signpdf').default const { pdfkitAddPlaceholder } = require('./helpers')

const createPdf = params => new Promise((resolve) => { const requestParams = { placeholder: {}, text: 'node-signpdf', addSignaturePlaceholder: true, pages: 1, ...params } const pdf = new PDFDocument({ autoFirstPage: false, size: 'A4', layout: 'portrait', bufferPages: true }) pdf.info.CreationDate = '' if (requestParams.pages < 1) { requestParams.pages = 1; } for (let i = 0; i < requestParams.pages; i++) { pdf.addPage().fillColor('#333').fontSize(25).moveDown().text(requestParams.text).save() } const pdfChunks = [] pdf.on('data', (data) => { pdfChunks.push(data) }) pdf.on('end', () => { resolve(Buffer.concat(pdfChunks)) }) const refs = pdfkitAddPlaceholder({ pdf, pdfBuffer: Buffer.from([pdf]), reason: 'I am the author', ...requestParams.placeholder }) Object.keys(refs).forEach(key => refs[key].end()) pdf.end() })

async function test() { const pdf = await createPdf({ placeholder: { signatureLength: 2, } }) pdf = signer.sign(pdf, fs.readFileSync(./resources/certificate.p12)) pdf.pipe(fs.createWriteStream('test.pdf')) pdf.end() }

(async () => { await test() })() `

any solution?

[petrkrizek]

downgrade to pdfkit@^0.10.0 solves this

[YATACOBLAS]

@petrkrizek thanks a lot, its work

[RdC1965]

@petrkrizek, yes, it works, thanks! Any news on why this could be happening?

@RdC1965 the pdfkit helper in the library was written for pdfkit 10. Version 11 support is on the way here https://github.com/vbuch/node-signpdf/pull/115

Thanks a lot, Valery.  I am looking forward to the upgrade. In the meantime, I am quite happy with version 10: it works perfectly. Regards, Rodrigo
