It creates objects for the import, but when accessing it it throws the error Cannot read properties of undefined (reading 'getSelf') from line in the getter:

let moduleRoot = window.moduleSpace[moduleName].getSelf;

So it seems like it thinks it’s there, but it hasn’t actually loaded in at all.

Short-term, a more useful error message would be useful for creators. But ideally, it would actually load in the import when createPerchanceTree is called.
