I am trying to get a list of fields and which fonts are assigned to them. I can use form.getFields() to get a list of fields in the form. I can then run through the "dict" to find the font name - Easy!
However, when I am working with a field that has "Child Fields", for example, a pdf with text fields of the same name, it does not have this font parameter.
It only has "/Kids" which contains some sort of reference I haven't been able to understand
I have also tried this:
createPDFAcroFields(fields\[1\].acroField.Kids())
However, it returns a blank array. Any help would be greatly appreciated.
Here's a jsFidle that grabs the fields and can show you the objects that are missing the font in the console!

const formPdfBytes = await fetch(formUrl).then(res => res.arrayBuffer())
// Load a PDF with form fields
const pdfDoc = await PDFDocument.load(formPdfBytes)
// Get the form containing all the fields
form = pdfDoc.getForm();
fields = form.getFields();
console.log(fields);
}
getFieldFonts();
