TypeError after upgrading Node version

Question

I'm trying to fix this problem for 6 hours now and I'm slowly starting to lose my mind, so please excuse my generic question.

First of all I am using:

Node: 8.10.0 | npm: 5.6.0 | Yarn: 1.5.1

I just upgraded my project to Node v8 and npm refused to install all dependencies, so i installed yarn which fixed the issue immediately.

My sources are compiled using Laravel Mix which utilises Webpack, Babel, ... internally.

Installing and compiling of my sources works perfectly fine now but for some reason my compiled js file is not working anymore (even if I downgrade to the previous Node version - 6.10.0).

Uncaught TypeError: fn.bind is not a function

I have aboslutely no ideas what this error means let alone what causes it.

I know that the error message is pretty generic and could probably mean a lot of things but hopefully someone knows what it means given my context.

Thanks!

Sometime when you upgrade libraries you have to adapt some code. As Javascript is not a typed language, the problem does't appears at compile time but at run time.

In your case, I suppose that you have a problem similar as this one.

Check which libraries yarn has upgraded and verify if some API has changed.
