also this : [![enter image description here][1]][1] when I run this code :

    var pdf = new chilkat.Pdf();
    var success = pdf.LoadFile("qa_data/pdf/hello.pdf");
    if (success == false) {
        console.log(pdf.LastErrorText);
        return;
    }
    var json = new chilkat.JsonObject();
    json.UpdateInt("signingCertificateV2",1);
    json.UpdateInt("signingTime",1);
    json.UpdateInt("page",1);
    json.UpdateString("appearance.y","top");
    json.UpdateString("appearance.x","left");
    json.UpdateString("appearance.fontScale","10.0");

    json.UpdateString("appearance.text[0]","Digitally signed by: cert_cn");
    json.UpdateString("appearance.text[1]","current_dt");
    var cert = new chilkat.Cert();
cert.UncommonOptions = "NoScMinidriver"
cspName = "TnTrust Token";
success = cert.LoadFromSmartcard(cspName)
    if (success == false) {
            console.log('TnTrust Token',cert.LastErrorText);
        return;
    }
    cert.SmartCardPin = "123456";
    success = pdf.SetSigningCert(cert);
    if (success == false) {
        console.log(pdf.LastErrorText);
        return;
    }
    success = pdf.SignPdf(json,"qa_output/hello_signed_hsm.pdf");
    if (success == false) {
        console.log(pdf.LastErrorText);
        return;
    }
    console.log("The PDF has been successfully cryptographically signed using an HSM.");
}

I uploaded a new build here: https://www.npmjs.com/package/@chilkat/ck-node14-win64 It is the version "9.50.89-hotfix1".

Please give it a try. Also, I see you are passing "TnTrust Token" to LoadFromSmartCard. If the problem remains, try passing an empty string. This should cause Chilkat to try using the default Microsoft CNG Storage Provider, which may have better success.
