I've found a core bug ✨ Detect external library assets rather than requiring manual type: external definition Needs work that identifies any library assets starting with http or https as "local files" and runs them through the localization system, which causes a fatal error, even though I've defined the library as external:
external:
js:
http://www.example.com: { external: true, minified: true }
We can workaround this by manually altering the libraries to set $data['type'] = 'external' before the parser. This also prevents the external libraries from being included in the CSS and JS aggregation.
Closed: works as designed

Oh noooo, it actually is documented as type: external and not external: true! This is not a bug.
