How to solve message "This page loads a script that uses the unsupported Ext JS Library"?

AI generated answer (using internal Slack threads):

The message "This page loads a script that uses the unsupported Ext JS Library" is a warning from NetSuite indicating that the Ext JS library, which you may be using in your SuiteScript code, will be removed in future NetSuite versions (specifically, NetSuite 2025.1). To resolve this issue, you have a few options: 1. Adjust your code to work without the Ext JS library: This is the most recommended solution. You should refactor your code to not rely on the Ext JS library. You can use other libraries that are supported by NetSuite, such as jQuery. 2. Replace the Ext JS library with your own external instance: If you still want to use the Ext JS library, you can upload your own version of ext.js to the file cabinet and reference it in your code. However, you need to license it from Sencha, the company that owns Ext JS. You can find more information on their website: https://www.sencha.com/products/extjs/. 3. Manipulate the DOM to remove the alert: This is a more complex solution and involves deploying your own client script that removes the alert via DOM manipulation. This solution is temporary and only needs to be done once. However, it requires a deep understanding of how the afterLoad function works. Please note that these solutions are based on the current state of NetSuite and may change in the future. Always refer to the latest NetSuite documentation for the most accurate information. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
