why?

I’ve got the same problem as @nikolaokonesh. I tried two browsers.

Chrome 71.0.3578.98 says:

Uncaught DOMException: Failed to execute 'querySelector' on 'Document': '/events/2' is not a valid selector.

Safari 12.0.2 (14606.3.4) says:

SyntaxError: The string did not match the expected pattern.

Both are refering to line 150 of bootstrap.js:

return selector && document.querySelector(selector) ? selector : null;

It seems to be a bug of bootstrap itself rather than the gem: twbs/bootstrap#27903

Exactly @wynksaiddestroy and the fix will be in our next release.

You can find a workaround here: twbs/bootstrap#27903 (comment)
