Issue submitter TODO list

Describe the bug (actual behavior)

I am trying to publish messages in the topic test with Value Serde Schemaregistry.

The following message is published successfully:

{"offerPrice": null,"customerOrderId":"6b39d152-c94c-13c4-8116-7f64136f2fa5"}

image

image

However, the following message is faild to be published:

{"offerPrice": "teststring","customerOrderId":"6b39d152-c94c-13c4-8116-7f64136f2fa5"}

image

Expected behavior

the message 

{"offerPrice": "teststring","customerOrderId":"6b39d152-c94c-13c4-8116-7f64136f2fa5"}

should pass the schema validation
