Answer 1

I had a similar error but not exactly the same described by other answers. I hope my answer can help someone.

I was importing a file in two components (angular 7 project):

Component 1:

LANGUAGES = require("../../models/LANGUAGES.json");

Component 2:

LANGUAGES = require("../../models/LANGUAGES.JSON");

This is a foolish mistake: the problem here is I'm using two differents requires on the same file with different capital letters (it generated a warning).

How to solve the problem ? Use the same model.

Component 1:

LANGUAGES = require("../../models/LANGUAGES.json");

Component 2:

LANGUAGES = require("../../models/LANGUAGES.json");

OR

Component 1:

LANGUAGES = require("../../models/LANGUAGES.JSON");

Component 2:

LANGUAGES = require("../../models/LANGUAGES.JSON");
