telescope: Undefined property: Illuminate\Cache\Events\KeyWritten::$seconds

Error Situation:

I have a brand new Laravel 5.7 project in which I have added make:auth. When navigating to /login route the application dies with Whoops reporting this error…

Undefined property: Illuminate\Cache\Events\KeyWritten::$seconds Thrown at: vendor/laravel/telescope/src/Watchers/CacheWatcher.php line 83

Conclusion

It looks like src/Watchers/CacheWatcher.php is calling the non existent property ‘seconds’ of the \Illuminate\Cache\Events\KeyWritten class. Only available properties are ‘key’, ‘value’, ‘tag’, and ‘minutes’.

        Telescope::recordCache(IncomingEntry::make([
            'type' => 'set',
            'key' => $event->key,
            'value' => $event->value,
            'expiration' => $event->seconds,
        ]));

My Environment Versions

PHP 7.2.15
Zend Engine v3.2.0 with Xdebug v2.6.1
MySQL  Ver 14.14 Distrib 5.7.22
Laravel 5.7.28

Everyone, please make sure to use Telescope 2.0 on Laravel 5.8, or Telescope 1.0 on Laravel 5.7.

@themsaid When I manually changed my composer.json to ‘>=1.0 <2.0.0’ it installed Telescope v1.1 and worked fine.

Agree with @RicardoRamirezR on mentioning the issue on installing Telescope for Laravel < 5.8 as it may save potential hours of head scratching and debugging for others.

May also want to remove ~5.7.7 from the composer.json file for dev-master since it breaks everything less than 5.8

jimigrunge on Feb 28, 2019

You’ll need to use Laravel 5.8 and Telescope 2.0, 5.8 is released already so if it’s a fresh project then start with it 😃

themsaid on Feb 28, 2019

If anyone wants a very fragile work around until they get a chance to update to 5.8 then this will work

Change

//CacheWatcher.php

        Telescope::recordCache(IncomingEntry::make([
            'type' => 'set',
            'key' => $event->key,
            'value' => $event->value,
            'expiration' => $event->seconds,
        ]));

        Telescope::recordCache(IncomingEntry::make([
            'type' => 'set',
            'key' => $event->key,
            'value' => $event->value,
            'expiration' => optional($event)->seconds ?? $event->minutes * 60,
        ]));

Of course if you composer update etc that will remove all the changes and you’re back to square one. As I said very fragile.

@laurencei we tagged a new version!

@themsaid Have similar error Undefined property: Illuminate\Cache\Events\KeyWritten::$minutes

Laravel 5.8 Telescope 3.0

solofeed on Feb 28, 2019

I’m in 5.7 and then did composer require laravel/telescopeit installed 2.0 since in telescope composer has "laravel/framework": "~5.7.7|~5.8.0" and Telescope 2.0 is not compatible with Laravel 5.7
