Description
When using a cache chain as an adapter we get an error when building the container.
How to reproduce
framework:
cache:
app: cache.chain
pools:
cache.chain:
adapters:
- cache.adapter.array
- cache.adapter.apcu
doctrine.result_cache_pool:
adapter: cache.appWhen warming up the cache we will get:
PHP Fatal error: Uncaught TypeError: Argument 1 passed to Symfony\Component\DependencyInjection\ChildDefinition::__construct() must be of the type string, object given, called in /project/vendor/symfony/cache/DependencyInjection/CachePoolPass.php on line 106 and defined in /project/vendor/symfony/dependency-injection/ChildDefinition.php:30
Stack trace:
#0 /project/vendor/symfony/cache/DependencyInjection/CachePoolPass.php(106): Symfony\Component\DependencyInjection\ChildDefinition->__construct(Object(Symfony\Component\DependencyInjection\ChildDefinition))
#1 /project/vendor/symfony/dependency-injection/Compiler/Compiler.php(91): Symfony\Component\Cache\DependencyInjection\CachePoolPass->process(Object(Symfony\Component\DependencyInjection\ContainerBuilder))
#2 /project/vendor/symfony/dependency-injection/ContainerBuilder.php(734): Symfony\Component\Dependency in /project/vendor/symfony/dependency-injection/ChildDefinition.php on line 30
Possible Solution
I have no possible solution at the moment.
Additional context
This could happen if you define your cache chain as cache.app (which I believe you should). Then other cache pools like the ones used by Doctrine will complain. A workaround is to tell doctrine to use another (non-chain) cache pool.
# config/packages/prod/doctrine.yaml

framework:
cache:
pools:
doctrine.result_cache_pool:
