Uncaught ReferenceError: docx is not defined

[dominodelarge]

docx.renderAsync() has stopped working, throwing a "docx is not defined" error.

No changes to code or scripts.

The document itself is generated successfully and can be downloaded in the browser, but it can no longer be previewed.

if (action === 'preview') {
            // Render the Word Document in the container. **(THIS FAILS)**
            docx.renderAsync(blob, document.querySelector("#modal-container"), null, docxOptions);
            $('#previewLetterModal').modal();

        } else if (action === 'download') {
            // Trigger the download of the generated document. **(THIS WORKS)**
            saveAs(blob, "hf-letter.docx");
        }

I am using the following libraries (which have remained unchanged for months):

<script src="https://unpkg.com/jszip/dist/jszip.min.js"></script>
<script src="https://volodymyrbaydalka.github.io/docxjs/dist/docx-preview.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/docxtemplater/3.40.1/docxtemplater.js"></script>

1. github is NOT cdn
2. docx-preview migrating to js modules. UMD module could be found under docx-preview.umd.js
