TypeError: The "original" argument must be of type Function

I am getting this error when trying to require tfjs-node in my electron react application. This issue wasn't happening before when I did not have react installed and I think it is due to something in the webpack require configuration.

const tf = require('@tensorflow/tfjs-node');

Error Log:

I am new to webpack and would appreciate any help and am happy to answer any clarifications needed as I do not know the source of the problem to be more detailed.

The issue is with the require. "@tensorflow/tfjs-node" exports multiple things(possibly), so the export inside this module would be something like 

module.exports = {
    firstThing,
    secondThing, ...
}

So, tf in your code is an object, and not a function. So, you should use named import like this,

const {tf} = require('@tensorflow/tfjs-node')

So, you are getting an error when invoking tf. I have not worked with this package, but this seems like the cause for error. If it doesn't fix the issue, please add the line that is throwing the error.
