[Cache] Cannot configure chain adapter #32139
Description
Symfony version(s) affected: 3.4.x
Description
When trying to configure a cache ChainAdapter I get the following error:
Argument 1 passed to Symfony\Component\Cache\Adapter\ChainAdapter::__construct() must be of the type array, string given, called in /project/root/var/cache/dev/ContainerMdWoD6O/getCache_GlobalClearerService.php on line 20
If I look in my container dump I see the following:
$this->services['cache.app'] = new \Symfony\Component\Cache\Adapter\ChainAdapter('y7VTFBCVw+', 2419200))
How to reproduce
composer create-project symfony/skeleton cache-issue
Add the following contents to cache.yaml:
framework:
cache:
# Put the unique name of your app here: the prefix seed
# is used to compute stable namespaces for cache keys.
#prefix_seed: your_vendor_name/app_name
app: cache.chain
pools:
cache.chain:
adapter: app.cache.adapter.chain
cache.array:
adapter: cache.adapter.array
cache.apcu:
adapter: cache.adapter.apcu
services:
app.cache.adapter.chain:
class: Symfony\Component\Cache\Adapter\ChainAdapter
arguments:
- [ '@cache.array', '@cache.apcu']
- 2419200 # One monthPossible Solution
I've debugged some but I cannot figure out a good solution nor the cause.
