Using UmbracoForms.Package.4.1.4 & Umbraco version 7.3.3.

I get this error on all the forms on the site

SyntaxError: JSON.parse: end of data while reading object contents at line 1 column 2 of the JSON data

    // Calling form this way.
    if (CurrentPage.HasValue("formGuid"))
    {
        Umbraco.RenderMacro("FormsRenderForm", new { FormGuid = @CurrentPage.formGuid })
    }

// script rendered by Umbraco Form
(function ($, formId, formName) {
    var contourFieldValues,

    This line --> recordValues = JSON.parse($("#values_" + formId).val()),

    fsConditions = JSON.parse($("#fsConditions_" + formId).val()),
    fieldConditions = JSON.parse($("#fieldConditions_" + formId).val()),
    form = $("#contour_form_" + formName);

Is there a fix to this?
