placement.split() is not a function

I’m getting this error when Popper 2 getBasePlacement(placement) function is used in popper.js.

On that function, placement should be an string before split() is used. This get fixed just changing return placement.split('-')[0]; to return placement.toString().split('-')[0];

@atomiks Thank you!! Adding type="module" to the script tag has fixed it.

In case it is useful to anyone: I am using Bootstrap’s tooltips but using the source files and my own bundling. I didn’t add the above because the Bootstrap docs specifically tell you not to, but I think that must just be if you’re using the pre-compiled version. If you’re using the source files and doing your own compiling, it’s not relevant and you should use type="module".

Thanks both @atomiks @doubleedesign, I was also making my own bundle for Bootstrap5, but adding type="module" to script tag fixed the issue.
