Was trying to use the javascript docx-templater-image module in https://github.com/evilc0des/docxtemplater-image-module-free, when just using the Demo browser code listed in the READ.ME, an Unhandled Promise Rejection: TemplateError: Multi error occurred in the browser console.

{"error":[{"message":"Attempted to assign to readonly property.","properties":{"file":"word/document.xml"},"line":323,"column":10,"sourceURL":"http://127.0.0.1:5500/build/imagemodule.js","stack":"addExtensionRels@http://127.0.0.1:5500/build/imagemodule.js:323:10\naddImageRels@http://127.0.0.1:5500/build/imagemodule.js:350:25\n@http://127.0.0.1:5500/build/imagemodule.js:164:38\npromiseReactionJob@[native code]"}]}

Still new to javascript so any help on its cause and how to solve it would be great!
