GetStateValidationParameter unexpected empty

fabric 2.4

The scenario

1. Prepare policy bytes by

var policy = ext.NewKeyEndorsementPolicy(nil)
policy.AddOrgs(msp.MSPRole_MEMBER, MSPIDs...)

3. SetStateValidationParameter with key a and policyBytes. I also did a double check here
4. After block commit is completed, I query on GetStateValidationParameter.
5. The result of GetStateValidationParameter is surprisingly empty.

In my first round test I submit and query via new fabric-gateway endpoint. So I suspect if it is issue from new gateway. But in second round test, even in tranditional way (specifying endorsing peers, eventing peers, orderer), this issue can be reproduced.
