Brunch error when optimizing bootstrap

Question

When I runbrunch b -o to optimize and build my project I get the following error:

JS minify failed on src/javascript/initialize.js: TypeError: Cannot call method 'active' of undefined

Which I have located is down to something inside bootstrap.js is there anything I can do to get around this issue or even better solve it?

Edit: Updated to latest stable version so now using brunch b -P but same issue.

Answer 1

Found a different version file for bootstrap everything seems to be working now.
