[alipowerful7]

wrong docblock:

    /**
     * Specify middleware that should be removed from the resource routes.
     *
     * @param  array|string  $middleware
     * @return $this|array
     */
    public function withoutMiddleware($middleware)
    {
        $this->options['excluded_middleware'] = array_merge(
            (array) ($this->options['excluded_middleware'] ?? []), Arr::wrap($middleware)
        );

        return $this;
    }

right docblock:

    /**
     * Specify middleware that should be removed from the resource routes.
     *
     * @param  array|string  $middleware
     * @return $this
     */
    public function withoutMiddleware($middleware)
    {
        $this->options['excluded_middleware'] = array_merge(
            (array) ($this->options['excluded_middleware'] ?? []), Arr::wrap($middleware)
        );

        return $this;
    }
