Circular dependency error

[Likhitha-03]

I am getting circular dependency error while containerizing this project

Causes:
Product.model.js relies on mongoose.
Product.Controller.js depends on Product.model.js.
app.js requires initDB.js, which in turn requires mongoose again, but mongoose is indirectly used in Product.model.js.

Errors:
(node:16732) Warning: Accessing non-existent property 'count' of module exports inside circular dependency
(Use node --trace-warnings ... to show where the warning was created)
(node:16732) Warning: Accessing non-existent property 'findOne' of module exports inside circular dependency
