Hi,  
I cannot produce a message with a self hosted Kafka REST Proxy v3.

Setup:

- Confluent standard cluster
- Deployed Kafka REST Proxy

I am trying to produce a record using my self managed Kafka REST Proxy with the following call:

`curl -X POST -H "Content-Type: application/json" "https://myhost.net/v3/clusters/mycluster/topics/mytopic/records" -d '{"key": "1", "value": "10"}'`

It returns:  
`{"error_code":404,"message":"HTTP 404 Not Found"}`

I don’t understand why this is not working. The code exists, the configuration seems to support v3 (listing topics with v3 does work), I am using my managed REST Proxy, and not a hosted one / Confluent’s. What am I missing here?

What version of Confluent are you using?

For what it’s worth, this worked for me against a 7.1.1 cluster:

```auto
curl http://localhost:8090/kafka/v3/clusters/MXeugl1RT6aI-2PdIze2fA/topics/test/records \
  -H 'content-type:application/json' \
  -X POST \
  -d '{"partition_id":0,"headers":[],"key":{"type":"BINARY","data":"Zm9vYmFy"},"value":{"type":"BINARY","data":"Zm9vYmFy"},"timestamp":"2021-02-05T19:14:42Z"}'

```

I am using a managed kafka cluster in Confluent, and a self managed REST Proxy (chart version 6.1). What do you mean by “version of Confluent”?

Besides, why would the cluster version matter? Producing with v2 (…/topics/mytopic) does work, so I’d expect v3 to work as well (uses the same producer if I’m not wrong).
