TypeError: Cannot read property 'kind' of

Question

This problem started to occur when updating my Angular 6 project to 7.x.

I opened an issue on the angular-cli github repo but they couldn't help.

So what I did is create a new project and add all components one by one to "hopefully" notice what caused the problem.

Unfortunately I couldn't identify the problem. Here's the log:

ERROR in : TypeError: Cannot read property 'kind' of undefined

Here's a link to the github issue with logs from a checkSourcefile function I was supposed to log:

How can I track down and (hopefully) fix what's causing this?
