I tried to connect to Redis in MemoryStore with GCP's CloudRun, but the error "ERR AUTH <password> called without any password configured for the default user. configuration is correct?"

The connection method is using Serverless VPC Access to connect Memorystore for Redis and Cloud Run.
In doing so, I got the error "ERR AUTH called without any password configured for the default user. configuration is correct?".
Here is the code. (Only the necessary parts are shown)

package main

import (
	"context".
	"github.com/go-redis/redis/v8"
)

func main() {
	ctx := context.Background()

	redisCl := redis.NewClient(&redis.Options{
		Addr: "xxx.x.x.x:6379",
		Password: "",
		DB: 0,
	})
}

Redis version 6.x series is used.
