Description

I'm trying to flush doctrine metadata using Redis adapter with Valkey 8.0.
TheRedisTrait sends the following query to Valkey:SCAN NULL on the first loop iteration, which leads to errorERR invalid cursor.

Shouldn't the cursor variable initialized to value0?
I've patched the file with$cursor = 0; instead, andbin/console doctrine:cache:clear-metadata works as expected.

How to reproduce

I'm using the following configuration:

doctrine:orm:metadata_cache_driver:type:poolpool:doctrine_redisframework:cache:pools:doctrine_redis:adapter:cache.adapter.redisprovider:snc_redis.doctrine_metadata_cachesnc_redis:clients:doctrine_metadata_cache:type:predisalias:doctrine_metadata_cachedsn:"%env(REDIS_URL)%/3"options:connection_timeout:10read_write_timeout:30

And runbin/console doctrine:cache:clear-metadata to get the error.

You can also use directlyvalkey-cli SCAN NULL

Possible Solution

Initialize the cursor variable with 0.
