Steps to reproduce

Use the following RepoConfig:

repo_config = RepoConfig(
    **{
        "project": "prod",
        "registry": {
            "registry_type": "sql",
            "path": os.getenv("DATABASE_URL"),
            "cache_ttl_seconds": 0,
            "sqlalchemy_config_kwargs": {
                "max_overflow": 50,
                "pool_size": 5,
                "pool_recycle": 3600,
            },
        },
        "provider": "aws",
        "entity_key_serialization_version": 3,
        "online_store": {
            "type": "hybrid_online_store.HybridOnlineStore",
            "routing_tag": "store",
            "online_stores": [
                {
                    "type": "dynamodb",
                    "conf": {
                        "region": "us-east-1",
                        "max_pool_connections": 50,

                    }
                },
                {

                    "conf": {
                        "connection_string": os.getenv("REDIS_URL")
                    }

            ],
        },
    }
)

Possible Solution

Use the following config:

repo_config = RepoConfig(
    **{
        "project": "prod",
        "registry": {
            "registry_type": "sql",
            "path": os.getenv("DATABASE_URL"),
            "cache_ttl_seconds": 0,
            "sqlalchemy_config_kwargs": {
                "max_overflow": 50,
                "pool_size": 5,
                "pool_recycle": 3600,
            },
        },
        "provider": "aws",
        "entity_key_serialization_version": 3,
        "online_store": {
            "type": "feast.infra.online_stores.hybrid_online_store.hybrid_online_store.HybridOnlineStore",
            "routing_tag": "store",
            "online_stores": [
                {
                    "type": "dynamodb",
                    "conf": {
                        "region": "us-east-1",
                        "max_pool_connections": 50,
                        "connect_timeout": 5,
                        "read_timeout": 10,
                        "total_max_retry_attempts": 2
                    }
                },
                {
                    "type": "redis",
                    "conf": {
                        "connection_string": os.getenv("REDIS_URL")
                    }
                }
            ],
        },
    }
)

Also, it's necessary to change the type attribute in hybrid_online_store.py (https://github.com/feast-dev/feast/blob/master/sdk/python/feast/infra/online_stores/hybrid_online_store/hybrid_online_store.py) from:

    type: Literal["HybridOnlineStore", "hybrid_online_store.HybridOnlineStore"] = (
        "hybrid_online_store.HybridOnlineStore"
    )

To:

    type: Literal["HybridOnlineStore", "feast.infra.online_stores.hybrid_online_store.hybrid_online_store.HybridOnlineStore"] = (
        "hybrid_online_store.HybridOnlineStore"
    )
