Describe the bug (actual behavior)

I'am using the Apicurio Schema Registry. After I create a JSON schema and try to send a message, I get the following error message:

Content NOT SUPPORTED: keyword "id", use "$id" for schema ID

JSON Schema:

{
  "$id": "https://training.com/EmployeeHasBeenCreatedEvent.schema.json",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "title": "EmployeeHasBeenCreatedEvent",
  "type": "object",
  "properties": {
    "id": {
      "type": "integer",
      "format": "int64",
      "description": "The employee's id."
    },
    "name": {
      "type": "string",
      "minLength": 1,
      "description": "The employee's name."
    }
  }
}

Reading messages based on the schema works well.

Expected behavior

Send the message.

• Is it just one of the schemas or json schemas don't work in general?
• Are you using SR compatible API in apicurio?

[vicziani]

• For all schema.
• What does it mean SR compatible? I'am using the Confluent Schema Registry API (Version 7) (/apis/ccompat/v7). As you see the Docker Compose file above:

KAFKA_CLUSTERS_0_SCHEMAREGISTRY=http://schema-registry:8080/apis/ccompat/v7

As you can see on the screenshots, the Kafka UI can download the schema, using it when consuming messages, create sample JSON based on the schema. It only throws error while producing message.

[vicziani]

I tried with another schema draft(http://json-schema.org/draft-07/schema#).

Kafka UI can download the schema, using it when consuming messages, create sample JSON based on the schema.

But another error message while producing message: Content no schema with key or ref "http://json-schema.org/draft-07/schema#". Kafka UI supports only the draft https://json-schema.org/draft/2020-12/schema?!

@Nilumilak can you take a look, please? It looks like a frontend issue, the validator either can't parse schema references or something.
