Seems the node does hot have the ability to use hyperlinks

Not that it doesn’t have hyperlinks, but that it hasn’t been updated for you Dynamo release and as such the code is attempting to pull something which isn’t valid in the given engine.

Ah thanks, so only for rvt2026 dynamo 3.4?

Specific context matters.

  1. Which version of Datashapes?
  2. Which Python engine(s) are you using?
  3. Which version of Revit (and thereby Dynamo)?

In the end I recommend either using the out of the box inputs for Dynamo player, or building your own UI as the Python based nature of Datashapes’ UI++ nodes means they are somewhat unreliable over time.

The node uses Ironpython2, tried switching to CPython3 but still fails. It just wants a string

Yeah - the old IronPython2 calls to things like webbrowser are more apt to fail in modern environments as the way it would have loaded .NET4 isn’t feasible in .NET8 which happend in Revit 2025+. Use of player will allow linking to external help sites (anything with https:\) as well as most standard inputs.
