I'm encountering an issue where the functions inside `ui_base.js` are not being called, even though the `init` function is executed. I’ve tried setting breakpoints in Node-RED, but they are not being hit.

**What I’ve tried:**

- Method 1: Tried debugging through Node-RED, but breakpoints in the `ui_base.js` file located at `/home/nandhini/CTCDSERV/nodered/node-red/node_modules/@flowfuse/node-red-dashboard/nodes/config/ui_base.js` aren’t working.
- Method 2: Used the CLI with `node --inspect ui_base.js` to try and debug the same file.

Any suggestions on how I can properly debug the `ui_base.js` file in Node-RED? Specifically, how can I ensure that breakpoints are hit and function calls are tracked?
