Element descriptor's .kind property "undefined" on Ember 3.6

[danieledraganti]

Hey there,
Just reporting a problem with lazy-mount on a freshly updated Ember 3.6 application. Using the standard ember-engines {{mount}} on a non-lazy loaded engine, I get no errors. Using {{lazy-mount}}, though, I get this:

[Error] TypeError: An element descriptor's .kind property must be either "method" or "field", but a decorator created an element descriptor with .kind "undefined"

Anyone else experiencing this?

Thanks.

What version of ember-cli-babel, @ember-decorators/babel-transforms and ember-cli-typescript are you using?

[danieledraganti]

"ember-cli-babel": "^7.2.0",
"@ember-decorators/babel-transforms@^3.1.5",
"ember-cli-typescript@2.0.0-rc.1".
Last two are not in my main package.json, but are sub-dependencies from who knows which packages.

Alright, thank you! I'll take a look soon.
