Confluent_Schema_Registry - Error, status 400

[Lucky38i]

Hi all,

We've recently been trying to use this library in our AWS Node Lambdas to register a schema and then encode with it.

const schema = await readAVSCAsync(getSchemaFromKey(s3ObjectKey))
const {id} = await registry.register({type: SchemaType.AVRO, schema})

However I keep running into a recurring error during the register method call with a status 400. The call being made by the library is perfectly valid so it's a bit perplexing why it would be returning 400 and there's no other logs for me to go off of.

{
    "errorType": "ResponseError",
    "errorMessage": "Confluent_Schema_Registry - Error, status 400",
    "name": "ResponseError",
    "status": 400,
    "unauthorized": false,
    "url": "get https://<confluent-url>/config/<subject>",
    "stack": [
        "ResponseError: Confluent_Schema_Registry - Error, status 400",
        "    at /var/task/index.js:2206:102",
        "    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"
    ]
}

I've tried making the exact same call via bruno and I get a 404 as expected as compatability has not been configured for the subject.

Any ideas?
