Error with acroForm

[Dennis-96]

Describe the bug and the expected behaviour When I try to create a pdf I get the acroform error.

Is it a bug in signing or in the helpers? Helpers

To Reproduce 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;
                }

                // Add some content to the page(s)
                for (let i = 0; i < requestParams.pages; i += 1) {
                    pdf
                        .addPage()
                        .fillColor('#333')
                        .fontSize(25)
                        .moveDown()
                        .text(requestParams.text)
                        .save();
                }

                // Collect the ouput PDF
                // and, when done, resolve with it stored in a Buffer
                const pdfChunks = [];
                pdf.on('data', (data) => {
                    pdfChunks.push(data);
                });
                pdf.on('end', () => {
                    resolve(Buffer.concat(pdfChunks));
                });

               // if (requestParams.addSignaturePlaceholder) {
                    // Externally (to PDFKit) add the signature placeholder.
                    const refs = pdfkitAddPlaceholder({
                        pdf,
                        pdfBuffer: Buffer.from([pdf]),
                        reason: 'I am the author',
                       // ...requestParams.placeholder,
                    });
                    // Externally end the streams of the created objects.
                    // PDFKit doesn't know much about them, so it won't .end() them.
                   // Object.keys(refs).forEach(key => refs[key].end());
              //  }

                // Also end the PDFDocument stream.
                // See pdf.on('end'... on how it is then converted to Buffer.
                pdf.end();
            });

ERROR UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'fonts' of undefined at PDFDocument.endAcroForm (node_modules\pdfkit\lib\mixins\acroform.js:78:37) at PDFDocument.end (node_modules\pdfkit\lib\document.js:311:10)

Thanks in advance for your help

Could this be because of the pdfkit version used? The helper is written for 0.10. There is this PR that is for 0.11

Thank you very much for the help @vbuch , now I am going to test it, I have one more question, was it possible to solve the problem so that the signature is visibly displayed in the pdf? , since I tried solutions with pdf-lib and failed to make this happen
