Is this scenario with scripts in external WARs supported?

If I put my script in a WAR called ua.war and deploy it I can access it
using a web browser, for example:

I have then tried to add it as a Global Script:

Type: external
Script: /ua/myscript.js
Workflows: X
Start Activity: X
Forms: X

I get this error when running my PRD in UA:
