Signature details null

[ghost]

Hello, i adapt your code signpdf.test.js to make it simpler, but when i use pdfsig to check the signature, the fields return null:

pdfsig bla.pdf 
Digital Signature Info of: bla.pdf
Internal Error (0): Input couldn't be parsed as a CMS signature
Syntax Error (0): Illegal values in ByteRange array
Signature #1:
  - Signer Certificate Common Name: (null)
  - Signer full Distinguished Name: (null)
  - Signing Time: Nov 18 2019 14:18:39
  - Signing Hash Algorithm: unknown
  - Signature Type: adbe.pkcs7.detached
  - Signature Validation: Signature has not yet been verified.

This is my code:

global.signpdf = require('node-signpdf'); 
global.PDF = require('pdfkit'); 
...
                doc = new PDF(.....);
                ....
                if (toSign) {

                    let fieldIds = [], form;
                    const signatureLength = 8192,
                            byteRangePlaceholder = '**********',
                            signature = doc.ref({
                                Type: 'Sig',
                                Filter: 'Adobe.PPKLite',
                                SubFilter: 'adbe.pkcs7.detached',
                                ByteRange: [
                                    0,
                                    byteRangePlaceholder,
                                    byteRangePlaceholder,
                                    byteRangePlaceholder
                                ],
                                Contents: Buffer.from(String.fromCharCode(0).repeat(signatureLength)),
                                Reason: new String("Blabla"),
                                M: new Date(),
                                ContactInfo: new String("bla@bla.pt"),
                                Name: new String('Bla'),
                                Location: new String('Bla')
                            }),
                            signatureName = 'Signature',
                            widget = doc.ref({
                                Type: 'Annot',
                                Subtype: 'Widget',
                                FT: 'Sig',
                                Rect: [0, 0, 0, 0],
                                V: signature,
                                T: new String(signatureName + (fieldIds.length + 1)),
                                F: 4,
                                P: doc.page.dictionary
                            });
                    doc.page.dictionary.data.Annots = [widget];

                    form = doc.ref({
                        Type: 'AcroForm',
                        SigFlags: 3,
                        Fields: [...fieldIds, widget]
                    });
                    doc._root.data.AcroForm = form;
                    signature.end();
                    widget.end();
                    form.end();
                }
                doc.end();
                const assinarPDF = new signpdf.SignPdf(
                        FS.readFileSync("./bla.pdf"),
                        FS.readFileSync(".bla.p12")
                        );
