Hi Experts, NetSuite has begun the process of removing the unsupported Ext JS library. If your customizations still rely on this library's API, it's crucial to prepare for its removal as soon as possible. To assist in identifying any usages of the Ext JS library within your account, a banner message will be displayed on pages that load scripts using this unsupported library. This feature is available in accounts running NetSuite 2024.2. I have several scripts deployed on a particular record. Could you please suggest how to identify which of these scripts are using the Ext JS library? Thank you for your assistance.

remove them all, add them back one by one until you find the one creating the banner

I have found that some older NetSuite bundles like file Drag n Drop are the biggest culprits. I pretty much assume anything running in SuiteScript 1.0 is most likely a cause for this.
