Describe the bug
After upgrading from Redis 7 to Redis 8 (with search and query included), FT.CREATE commands from a redis function (lua) fail with "Cannot perform FT.CREATE: Cannot block"

To Reproduce
Steps to reproduce the behavior:

1. Run a 6 node Redis 8 cluster in Docker (using redis:latest image) with RediSearch loaded in config
2. Load a Redis function like

local function add_instance(keys, args)
    local gameId = keys[1]

    local indexResult = redis.pcall(
        "FT.CREATE", "idx:g:{" .. gameId .. "}:instances", "ON", "HASH",
        "PREFIX", 1, "g:{" .. gameId .. "}:i:", "SCHEMA",
        "instanceId", "TAG",
        "protocolVersion", "NUMERIC",
        "gameVersion", "TAG",
        "region", "TAG",
        "playerCount", "NUMERIC", "SORTABLE",
        "priority", "NUMERIC", "SORTABLE",
        "privateInstanceHostId", "TAG",
        "customQueueEligibleList", "TAG"
    )
end

3. FCALL this function with a gameId key and receive "error":"Cannot perform FT.CREATE: Cannot block"

Expected behavior

• Ability to create index from lua on a cluster using the {} to ensure we're operating on the same slots as the key passed.

Environment (please complete the following information):

• Version/branch Redis 8.0.2 with included RediSearch

Additional context

• Our Redis 7 cluster where this works is running with SAFEMODE enabled. I could not find any such config option (or similar concurrency controls) with the latest version
