Thanks for opening this issue! Downloading of the published package from NPM and bundling it with webpack does work. I will update the dist file here on GitHub asap.

Edit:
The error is coming from the buffer dependency.

I have this issue on 1.2.2 downloaded from NPM and bundled with webpack. I didn't have the issue with 1.2.1.

The error appears when web3.js receives a confirmation of a transaction.

Regression?
