Tether Error: Both element and target must be defined

[slorber]

I'm using Browserify with TetherTooltip.
require("tether-tooltip/tooltip"); works fine to get the code.

However, Tether gives me the error Tether Error: Both element and target must be defined

Versions are:

/*! tether-tooltip 0.2.6 */
/*! tether 0.6.5 */

Notice that I have this error even with the code sample

new Tooltip({
  target: targetElement,
  position: 'top left',
  content: "My awesome <b>content</b>.",
  classes: 'my-tether-theme'
});

I see in my debugger the call to setOptions with the attributes

options: Object
  classes: "my-tether-theme"
  content: "My awesome <b>content</b>."
  position: "top left"
  target: div.space-overview-shared-with-count

So is it a bug? At least I don't understand what I am supposed to pass as element

Actually it's not a bug with Tether or Tooltip, it's a problem when using the NPM package with browserify.

Any fix for this?
