Hello,
I have been hunting down the error
loader.js:247 Uncaught Error: Could not find module
ember-cli-htmlbars
imported fromsomecomponent
in an addon for the last days after migrating to new ember version including octane.
Finally I found the cause:
included: function (app, parentAddon) {
in the file index.js is causing the problem.
Any example how this should be changed now?
