Missing information in the developer console

the following error message appears in the developer console: (node:1) [MODULE_NOT_FOUND] Error: Your application tried to access debug, but it isn’t declared in your dependencies; this makes the require call ambiguous and unsound.
(Use node --trace-warnings ... to show where the warning was created)

The problem is:
the message is beautiful, but what is the missing module? Is it too hard to say?
