BitCount return ERR syntax error

[ViolaPioggia]

I use go-redis with BitCount like this but return ERR syntax error

res, err := svc.Svc.Rdb.BitCount(ctx,
	fmt.Sprintf("%s%s",
	jwzxconsts.RdbKeyNewsRead,
	item.Id,
	),
	&redis.BitCount{
	        Start: 0,
		End:   -1,
	},
).Result()

Expected Behavior

return bitcount value normally

Current Behavior

return ERR syntax error

Possible Solution

My current go-redis version is v9.5.1(newest) , when I roll back to the v9.3.0 , this problem is soluted

redis v7.0.0 bitcount add a field 'Unit' , and In go-redis v9.5.1 it will add this field automically, but my redis version is below v7.0.0
so that it returned ERR syntax error

Context (Environment)

go version: 1.21.8
redis version: 6.2.8
go-redis version: 9.5.1

Detailed Description
