[14:40:52] Sorry, but there was a problem during parsing or generation of the documentation. 

Operating System, Node.js, npm, compodoc version(s)

Mac 10.15.5, Node v12.14.1, compodoc 1.1.11

Angular configuration, a package.json file in the root folder

Compodoc installed globally or locally ?

I tried globally and locally.

Tried both:

• npm run doc (package.json: "doc": "compodoc -p src/tsconfig.app.json")
• npx compodoc -p src/tsconfig.app.json

If possible sourcecode of the file where it breaks

unsure what the problem is - none of my files appear in the stack trace

If possible your terminal logs before the error

Motivation for or Use Case

first run error

Reproduce the error

🤷

Suggest a Fix

No clue 😅

A year or more back I tried the project and it worked 👍

During global installation there was some error about xcode(?) not being present?
