I am using Laravel 5.7 and... well, this error is happening because of a library that i am using right now: highideas/laravel-users-online in which this function:

public function setCache($minutes = 5)
 
 return Cache::put($this->getCacheKey(), $this->getCacheContent(), $minutes);
 

Throws the next error:

Serialization of 'Closure' is not allowed

The two functions that it uses are:

public function getCacheContent()
 
 if (!empty($cache = Cache::get($this->getCacheKey()))) 
 return $cache;
 
 $cachedAt = Carbon::now();
 return [
 'cachedAt' => $cachedAt,
 'user' => $this,
 ];
 

And:

public function getCacheKey()
 
 return sprintf('%s-%s', "UserOnline", $this->id);
 

Is there a way to fix this error?

  What's in here $this->getCacheContent()? Cache::put('key', 'value', $min); requires second parameter to be string

  The FileStore.php file says that the second parameter "value" is a mixed, not a string

  Oh sorry, missed that. It's returning an array, however the required parameter should be string. You can try serialize($this->getCacheContent()) to convert array to string

  Cache::put will already call serialize internally. I suspect issue is related to the user variable, which contains some data which cannot be automatically serialized.
