The error message is telling you the problem. You’re calling ->id on a variable that’s a collection; not a model.

So go to the line the error message will have highlighted. The variable on that line is a collection, and not a model like you think it is.

the error appers while sedding like from the terminal like that

all what i see here is the line in the Internal code of larvel not in my code

It’s probably this line:

->for(Category::factory()->count(3))

That’s not how you use the for method. You should be passing a single model there; not a factory that creates 3 models. So that is probably going to return a collection.
