我需要以编程方式填写PDF表单单选按钮，我可以在JS，go或python中执行此操作吗？

I found pdf-fill-form for node.js and am using that well for filling out a PDF application that a client needs to match the user's online application. The only issue is that the pdf has a few radio buttons, like for gender, and I get no response when I try and set the field "Sex" value to "Male" or "Female" even though those are the values.

  var vals = {"Sex": "Male"}

  pdfFillForm.write(sourcePDF, vals, { "save": "pdf" } )
    .then(function(result) {
      fs.writeFile(destinationPDF, result, function(err){
        if (err) {
          return console.log(err);
        }
        console.log("Success Saving");
      });
    }, function(err) {
      console.log(err);
  });

It says clearly in pdf-fill-form documentation that it only supports text and checkboxes so I get it, but I can't find anything outside of Java or C#/C++ that can do this, and I really don't want to add another technology to solve what seems like a fairly common problem. Anyone know of anything? Or is there a work around? Thanks.

I made the fix myself, actually wasn't to bad. I just updated the pdf-fill-form code, and am waiting to hear back about my pull request, but if anyone needs it in the meantime, https://github.com/mttchrry/pdf-fill-form
