ErrorException: Trying to get property 'id' of non-object --Laravel unit test

Question

Recently I am working on a project 'facebook-clone' using Laravel and vue.js. I have been using unit test for the first time. After performing the test I found this error,

Error: "ErrorException: Trying to get property 'id' of non-object"

For sending a friend request I wrote this

test.a_user_can_send_a_friend_request

I am using many to many relationships in User Model.

many to many relationships within users model

this is the pivot table friends

Api route:

api.php

The Controller used:

FriendRequestController

The resource used:

Friend

Answer 1

The problem is solved, I made a mistake in FriendRequestController where I should have passed an argument in Friendesource, instead I passed an array by mistake.

With error:

return new FriendResource([
        Friend::where('user_id', auth()->user()
        ->id)->where('friend_id', $data['friend_id'])
        ->first()
    ]);

after fixing error:

return new FriendResource(
        Friend::where('user_id', auth()->user()
        ->id)->where('friend_id', $data['friend_id'])
        ->first()
    );
