While experimenting with the pubsub CreateTopic API, I accidentally sent a version of the following (golang-based) topic:
ct_rsp, err := sconn.CreateTopic(&sns.CreateTopicInput{
Name: aws.String(topic),
Attributes: map[string]*string{
"verify-ssl": aws.String("false"),
"use-ssl": aws.String("false"),
"kafka-ack-level": aws.String("none"),
"push-endpoint": aws.String("kafka://lemon:9092"),
"persistent": aws.String("false"), // for now!
},
})
with push-endpoint set to "lemon:9092"--i.e, missing the scheme portion of the url.

Naturally this fails, but I was surprised when it crashed the golang program trying to create the topic:

I think this indicates a problem with the error document RGW is returning, though I don't see the issue offhand...
