Node module in Rails project potentially caching old version?

I am working on a Rails project that uses flexicious-react-datagrid and flexicious-react-datagrid-styles node modules. These modules are referenced in the package.json as:

"dependencies": {
...
"flexicious-react-datagrid": "file:./npm_libs/flexicious-react-datagrid",
"flexicious-react-datagrid-styles": "^1.2.0",
...
}

The problem I have is manually updating one of the modules to a licensed version.

The flexicious-react-datagrid module is a trial version, which after some amount of time working with it, it has now expired and gives a popup with ErrorCode103 when trying to load the page and some infinite loop runs so the page becomes stuck loading forever.

The Flexicious team provides the licensed version by providing a react-datagrid.min.js file that contains the licensed code. Even though I replace this in the node module, The error still occurs.

This makes it seem like it's caching the old code server-side, since the code that would invoke the ErrorCode103 popup should be from the code that was replaced. I've tried loading in incognito or other browsers with no luck.

Our project uses browserify, and I have some suspicion (but not sure) that this may be what is caching the module. I haven't had any luck trying to find what is causing this issue so far.
