Update SupportsUptimeCheck.php to handle clone error on non object value

[syofyanzuhad]

__clone method called on non-object

70         $this->uptimeCheckFailed($reason);
71     }
72 
73     public function uptimeCheckSucceeded(): void
74     {
75         $this->uptime_status = UptimeStatus::UP;
76         $this->uptime_check_failure_reason = '';
77 
78         $wasFailing = ! is_null($this->uptime_check_failed_event_fired_on_date);
79         $lastStatusChangeDate = $this->uptime_status_last_change_date ? clone $this->uptime_status_last_change_date :null;
80 
81         $this->uptime_check_times_failed_in_a_row = 0;
82         $this->uptime_last_check_date = Carbon::now();
83         $this->uptime_check_failed_event_fired_on_date = null;
84         $this->save();
85 
86         if ($wasFailing) {
87             $downtimePeriod = new Period($lastStatusChangeDate, $this->uptime_last_check_date);
88 
89             event(new UptimeCheckRecovered($this, $downtimePeriod));

It's fixed with adding cast to the uptime_status_last_change_date column on monitoring custom model

<?php

namespace App\Models;

use Spatie\UptimeMonitor\Models\Monitor as SpatieMonitor;

class Monitor extends SpatieMonitor
{
    protected $casts = [
        'uptime_check_enabled' => 'boolean',
        'certificate_check_enabled' => 'boolean',
        'uptime_last_check_date' => 'datetime',
        'uptime_status_last_change_date' => 'datetime',
        'uptime_check_failed_event_fired_on_date' => 'datetime',
        'certificate_expiration_date' => 'datetime',
    ];
