How to Add Signature Form Field to PDF in Node.js using Aspose.PDF REST API

Aspose.PDF Cloud Product Family

I am receiving the following error when trying to add a Signature Form Field:
text: ‘{“RequestId”:“daa0408b-f2c0-4253-8af2-a48ea41da8a8”,“Error”:{“Code”:“internalError”,“Message”:“Object reference not set to an instance of an object.”,“Description”:“Operation Failed. Internal error.”,“DateTime”:“2021-04-08T02:17:57.2478794Z”,“InnerError”:null}}’,

Using:

const signature = new Signature();
        signature.authority = "Linqed-IQ";
        signature.contact = "ppayne@linqed-iq.com"
        signature.date = "08/01/2012 12:15:00.000 PM";
        signature.formFieldName = "Signature1";
        signature.location = "United States";
        signature.password = "test1234";
        signature.rectangle = { lLX: 100, lLY: 100, uRX: 500, uRY: 500 };
        signature.signaturePath = "Linqed-IQ.pfx";
        signature.signatureType = SignatureType.PKCS7;
        signature.visible = true;
        signature.showProperties = true;
        signature.Signature1 = 'LinqedIQ Development';
        //signature.pageIndex = 1;

        const signatureField = new SignatureField();    // https://github.com/aspose-pdf-cloud/aspose-pdf-cloud-node.js/blob/master/docs/SignatureField.md -->
        signatureField.pageIndex = 1;
        
        pdfApi.putSignatureField('test1.pdf', 'Signature1', signatureField, null, remoteFolder).then((result) => {
            console.log(result.response);
        }).catch(function(err) {
            // Deal with an error
            console.log(err);
            console.log('COPY ERROR!');
        });

I am not sure how to resolve this error. Do you have a working example of this API operation on Node.js?

ALSO: I reached my 150 API limit on my Free account. Either I need it temporarily extended during my trial, or I need assistance. When I enter in CC details, it keeps giving me an error that a card needs to be on file (it is), so something not working with CC input forms for upgrade. I left a VM as well on sales #.

Please note you are not creating the new SignatureField properly so getting the exception while updating the signature field. Please checks sample putSignatureField unit test for reference.
