Need help - Axios - Uncaught (in promise) Error: Request failed with status code 500

[Newbie7]

Hello,
I am working on the freecodecamp Laravel project linked below:

Laravel PHP Framework Tutorial - Full Course for Beginners (2019)

Everything worked fine until 3:30:57 (time in the YT lecture).
Instead of getting the propper alert I get errors:

POST http://127.0.0.1:8000/follow/1 500 (Internal Server Error)
dispatchXhrRequest @ app.js:285
xhrAdapter @ app.js:119
dispatchRequest @ app.js:765
Promise.then (async)
request @ app.js:542

followUser @ app.js:1924
invokeWithErrorHandling @ app.js:39508
invoker @ app.js:39833
original._wrapper @ app.js:45192

Uncaught (in promise) Error: Request failed with status code 500
at createError (app.js:699)
at settle (app.js:960)
at XMLHttpRequest.handleLoad (app.js:168)
createError @ app.js:699

Promise.then (async)
followUser @ app.js:1924
invokeWithErrorHandling @ app.js:39508
invoker @ app.js:39833
original._wrapper @ app.js:45192

In my index.blade,php file I have:

<follow-button user-id="{{$user->id}}"></follow-button>

In my FollowButton.vue I have:

<template>
    <div>
        <button class="btn btn-primary ml-4" @click="followUser">Follow</button>
    </div>
</template>

<script>
    export default {

        props:['userId'],

        mounted() {
            console.log('Component mounted.')
        },

        methods: {
            followUser() {

                    axios.post('/follow/' + this.userId)
                .then(response => {
                    alert(response.data);
                });

                }
            }

    }
</script>

In my web.php I have:

Route::post('/follow/{user}', 'FollowsController@store');

In my FollowsController.php I have:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FollowsController extends Controller
{
    public function store(User $user)
    {
        return $user->username;
    }
}

I hope someone here could help me resolve this.
Thanks.

Hello! Welcome to the community !

You would need to check the error log to understand what happens . An error 500 means that the server throw an exception from which it could not recover.

Where the error_log is will depend on your project configuration. It may be in /var/log/apache/error_log (if you connect through SSH to homestead).

Thank you!
And regarding this matter…
I don’t use homestead at the time.
The whole project is in the local folder C:\cmder\freeCodeGram
The only log file I found so far was laravel.log
This is my first Laravel project, by the way.

It seems that laravel.log contains all the relevant information.
Searching through the file for “error”, I found this:

[2020-09-08 15:12:12] local.ERROR: Target class [App\Http\Controllers\User] does not exist. {"userId":3,"exception":"[object] (Illuminate\\Contracts\\Container\\BindingResolutionException(code: 0): Target class [App\\Http\\Controllers\\User] does not exist. at C:\\cmder\\freeCodeGram\\vendor\\laravel\\framework\\src\\Illuminate\\Container\\Container.php:811)
[stacktrace]

What should I do now?

[Newbie7]

Just to let you know - I figured this out myself.
There was line of code missing in the FollowsController.php

use App\User;

And that was all.
It’s working fine again.

I’m happy you solved it by yourself, so congratulations !

One thing that will work for every project: find and read the applicaiton logs (whatever and however the application/software/OS keeps them). There’s always one .

PD: sorry for not replying before, I forgot to track the thread ! You should, however, reply to the posts of others so they get notified regardless .
