office.js:76 Uncaught Error: Office.js has not fully loaded. Your app must call "Office.onReady()" as part of it's loading sequence (or set the "Office.initialize" function). If your app has this functionality, try reloading this page.

I'm developing a Word Add-in using the Yeoman generator and have integrated custom APIs for the authentication flow. Although I've implemented Office.onReady() in both my main platform and within the Add-in code, I’m consistently encountering the following error: "office.js:76 Uncaught Error: Office.js has not fully loaded. Your app must call "Office.onReady()" as part of its loading sequence (or set the "Office.initialize" function). If your app has this functionality, try reloading this page." I'm unsure why this is happening, since Office.onReady() is already being used as recommended. I haven’t been able to find a solution or workaround for this issue. Any guidance on resolving this would be greatly appreciated.
