Converting form data to JSON

Question

I am building a search form, and I want to use JSON formatting of the search fields to call a generic web handler using AJAX. My current challenge is this - I am using the following form code:

<form id="frmSearch" class="was-validated" method="post">
            <div class="row mb-4">
                <div class="col-lg-2 offset-lg-1 text-end">Find companies where...</div>
                <div class="col-lg-2 text-start">
                    <select ID="ddlType" Class="form-control rounded" required>
                        <option value="" selected>Search by...</option>
                        <option value="company_name">Company Name</option>
                        <option value="city">City</option>
                        <option value="federal_ein">EIN</option>
                        <option value="state">State</option>
                    </select>
                </div>
                <div class="col-lg-1 text-center">contains...</div>
                <div class="col-lg-4 d-flex">
                    <input type="text" ID="tbTerm" class="form-control rounded text-black" required />
                </div>
                <div class="col-lg-1 mx-auto">
                    <input type="submit" ID="btnSearch" class="btn-success btn text-white" text="search" />
                </div>
            </div>
        </form>

Then, using an example I found here on SO, I am using jQuery to format the form fields to JSON, like so:

            $(function () {
                $('#frmSearch').submit(function () {
                    alert('got here');
                    var txt = JSON.stringify($('#frmSearch').serializeObject());
                    alert(txt)
                });
            })

The problem is, the alert triggers, so I know the code is executing, except the Stringify fails silently, and the second alert never triggers. I don't get any errors in the console. Any help here as to why this is happening?

I've never used jquery, nevertheless googling and with personal knowledge i came up with this.

 $(function () {
              $('#frmSearch').submit(function (event) {
                event.preventDefault();
                object= {}
                formData = new FormData(event.target);
                formData.forEach((value, key) => object[key] = value);
                alert('got here');
                var txt = JSON.stringify(object);
                alert(txt)
              })
 });

I hope i have been able to help you! Regards.
