Understanding in client how validation works when we define any schema in producer #411

in existing example if we see producer-schema.js where we are setting JSON schema for the topic by producer
and let say I enabled enforceValidation from pulsar-admin to true
so now I am expecting if producer is trying to send message which dosent not follow the schema client should throw an error validation failed
for example if producer is trying to send message
producer.send({
data: Buffer.from(JSON.stringify({"a":"testXYZ","b":1})),
});

for topic schema validation is already enabled
with below command

bin/pulsar-admin namespaces set-schema-validation-enforce --enable tenant/namespace

as we can see a should be integer but I am passing string
so I am expecting that pulsar or client should throw validation error instead of sending this message successfully?
same case from consumer side too
