Leaving this here for any future Googlers:

I was also encountering this issue. I was passing an array of strings to a smart contract write call, and hitting the exception ‘str.charCodeAt is not a function’. It turns out I was using the wrong smart contract name - I was using one that expected just a string, and not an array.

@mayuranganesathas I think that’s your best bet; the stacktrace is powerful. Make sure you use a non-minified version to keep your headaches to a minimum. 😃
