I currently have Kafka and confluent downloaded via the information on the confluent quickstart page

I can run Kafka, create consumers/producers, and access everything via the confluent control center at localhost:9021

I am now attempting to use the schema registry. I can create a topic and add a schema to it. I can validate the schema as well.

However, when I change the setting within a topic to make schema value verification true instead of its default value of false, it does not work.

I receive the following error:

**confluent.key.schema.validation and / or confluent.value.schema.validation is enabled but there is no confluent.schema.registry.url specified at the broker side, will not add the corresponding validator**

I attempted to solve this:

I used [https://docs.confluent.io/platform/current/schema-registry/schema-validation.html](https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.confluent.io%2Fplatform%2Fcurrent%2Fschema-registry%2Fschema-validation.html&data=05%7C01%7Caghanima%40visa.com%7C10ee85f8b0f449a8b11e08da6e6e9b24%7C38305e12e15d4ee888b9c4db1c477d76%7C0%7C0%7C637943718610830833%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=nzeWadkMkl4YBdIEkHJGs9GxW%2FqRGP0NoIlSUlYWKtU%3D&reserved=0) and placed confluent.schema.registry.url=http://schema-registry:8081in the appropriate file. This allowed me to create topics with a schema and change the default value to false, but I also received errors when trying to publish the schema.

The schema-registry:8081 does not lead to anything and localhost:8081/leads to a black page with empty curly braces. I attempted to replace schema-registry:8081 with localhost:8081 but that did not work either.

In all these cases, I am unable to reject bad data from a producer via the built-in produce to a topic button.

I am not sure what the issue is. I would appreciate any help.

@lavalex The original post hit a few issues (Schema Registry config, errors registering schema, and then schema validation itself not working). Can you share details on the specific problem that you’re hitting and repro steps?
