Is there a conflict between GuzzleHttp and Laravel Sanctum?

Question

I have two laravel projects. The first one is an API which works perfectly. This is my login method:

/**
 * Login api
 *
 * @return JsonResponse
 */
public function login( LoginRequest $request ) : JsonResponse
{
    $remember = $request->has( 'remember' );

    if( Auth::attempt( [
            'username' => $request->username,
            'password' => $request->password,
        ], $remember )
    ){
        $user = Auth::user();
        $user->tokens()->delete();
        $success = [
            'token' => $user->createToken( config( 'app.name' ) )->plainTextToken,
            'user' => new UserResource( $user ),
        ];

        return $this->sendResponse( $success, __( 'users.auth.login-succesful' ) );
    }
    else{
        return $this->sendError( __( 'users.auth.login-failed' ), [], 401 );
    }
}

When I use postman to verify, everything is peachy, I send this POST request to the login page:

    {
        "username" : "someones_username",
        "password" : "**secure_pass123",
        "remember" : true
    }

And I get this response from the API (which is the expected one):

    {
        "success": true,
        "data": {
            "token": "1|FH2T3Hrv1zEWu4nVDFx6jCjTV5oY2yJUQfNKgexT",
            "user": {
                "username": "someones_username",
                "person": {
                    "name": "User",
                    "last": "Lastname",
                    "slug": "user-lastname",
                    "document_number": "00000000",
                    "document_type": {
                        "id": 1,
                        "slug": "id-card",
                        "short": "ic",
                        "name": "Identification Card",
                    }
                },
                "permissions": []
            }
        },
        "message": "users.auth.login-succesful"
    }

Now, when I request the Login URL from my Admin project, I get a 500 error message. But it is really weird, because the error starts with this:

[2022-03-16 05:29:53] local.ERROR: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'users.deleted_at' in 'where clause' (SQL: select * from `users` where `users`.`deleted_at` is null limit 1) {"exception":"[object] (Illuminate\\Database\\QueryException(code: 42S22): SQLSTATE[42S22]: Column not found: 1054 Unknown column 'users.deleted_at' in 'where clause' (SQL: select * from `users` where `users`.`deleted_at` is null limit 1) at C:\\webdev\\projects\\api\\vendor\\laravel\\framework\\src\\Illuminate\\Database\\Connection.php:716)

Of course the column exists. I tried dumping the LoginRequest $request and it has all the data. So I don't really know what is going on. The .env is correct, it is referencing the correct database.

I am using Laravel Sanctum in my API and GuzzleHttp in my Admin.

I have activated the SoftDeletes trait in my Model,but the deleted_at column does exist in my migrations. Here is the up method in my CreateUsersTable:

public function up()
{
    Schema::create( 'users', function( Blueprint $table ){
        $table->id();
        $table->string( 'username' )->unique();
        $table->string( 'password' );
        $table->rememberToken();
        $table->json( 'data' )->nullable();

        $table->foreignId( 'person_id' )->constrained( 'people' );

        $table->timestamp( 'email_verified_at' )->nullable();
        $table->timestamp( 'deactivated_at' )->nullable();
        $table->softDeletes();
        $table->timestamp( 'created_at' )->useCurrent();
        $table->timestamp( 'updated_at' )->useCurrent()->useCurrentOnUpdate();
    } );
}

And my User class goes like this:

class User extends Authenticatable
{
    use Activable, HasData, HasApiTokens, HasFactory, HasRoles, Notifiable, SoftDeletes;
    ...
    ...
}

The LoginController in my Admin:

    /**
     * Tries to login the user
     *
     */
    public function login( Request $request )
    {
        $params = request( [ 'username', 'password', 'remember', ] );
        return $this->requestURL( 'login', 'POST', $params, [
            'Content-Type' => 'application/json',
        ] );
    }

    public function requestURL(
        string $url, string $method = 'POST', array $params = [], array $headers = []
    )
    {
        $client = new Client(); //GuzzleHttp\Client
        $url = config( 'superveci.api' ) . '/' . $url;
        $headers = $this->makeHeaders( $headers );
        return $client->request( $method, $url, [
            'json'    => $params,
            'headers' => $headers,
            'verify'  => false,
        ] )->getBody();

    }
