HTTP Sink Connector and DLQ

Hello,

I have a working HTTP Sink connector 1.7.4 (latest), with these settings:

errors.tolerance: “all”
errors.deadletterqueue.topic.name: “dlq-httpsink”

The topic is created when connector starts, but if I get an error from the HTTP server, nothing goes to the dlq.

What am I missing?

Thank you.
