[3.0.0-beta.3] Cannot read properties of undefined (reading 'extend') at link-to.js

[johanrd]

When running an app with ember-mobile-menu 3.0.0-beta.3 from embroider 1.5.0 and ember-source 4.3.0, I get the following error:

TypeError: Cannot read properties of undefined (reading 'extend') at 
eval (webpack://webapp/./node_modules/ember-mobile-menu/components/mobile-menu/link-to.js?:15:143)

Maybe be related to #229? or some build / package.json entanglement happening with the recent migration to monorepo? (I see there is a package.json both in root and in /addon). Please tell me if you are not able to reproduce – I'll try to create a minimal reproduction.

I think it may be this emberjs/ember-legacy-built-in-components#9 (comment) . Do you have older embroider deps in your lock file? You could try to add a resolution/override for them.

edit: verified to work correctly in a clean ember 4 + embroider optimized app

OK, thanks, yes. Was fixed by deleting and recreating my lock file. Thanks!
