Uncaught ReferenceError: ClipboardItem is not defined

Hi HasnainNutkani ,

Thank you for reaching out to the Microsoft Fabric Community.

The error message Uncaught ReferenceError: ClipboardItem is not defined is not caused by the Power BI JavaScript embedding functionality itself. Rather, it originates from usage of the Clipboard API specifically the ClipboardItem interface which is a browser-provided feature not supported in all environments.

This API is not part of the Power BI SDK, so the error is likely coming from custom application code or a third-party script that is being executed alongside or during the embedding process. As your integration has been stable for years, it’s possible that a recent change such as a browser update, added dependency, or modification in your app introduced this usage. It's also important to ensure the application is running in a secure (HTTPS) context and in a browser that supports the Clipboard API.

If the Power BI reports are rendering correctly and the error is only appearing in the console, it may be a non-blocking issue. However, if the embedding is being affected, we recommend reviewing any recent changes made to your app or libraries and checking the browser’s developer tools to locate the specific source of the error.

I hope this will resolve your issue, if you need any further assistance, feel free to reach out.
