After starting the pubsub emulator, I'm trying to create a topic and a subscription using the HTTP API. Creating a topic succeeds, but I cannot figure out why creating a subscription doesn't. Am I doing something wrong or is this a bug in the tool? You can see the logs below:

$ curl -s -X PUT http://localhost:8085/v1/projects/myproject/topics/mytopic
{
  "name": "projects/myproject/topics/mytopic"
}

$ curl -s -X PUT http://localhost:8085/v1/projects/myproject/subscriptions/mysub \
    --data '{"topic":"projects/myproject/topics/mytopic"}'
Not Found

On the emulator side, I see the following:

# create topic logs
[pubsub] Apr 29, 2020 10:37:19 AM io.gapi.emulators.grpc.GrpcServer$3 operationComplete
[pubsub] INFO: Adding handler(s) to newly registered Channel.

Even though creating a topic works with the above command (no content type necessary), in order to send data with the --data '...' option, you also need to send the content type header. So the following command does work:

$ curl -s -X PUT http://localhost:8085/v1/projects/myproject/subscriptions/mysub \
    -H 'content-type: application/json' \
    --data '{"topic":"projects/myproject/topics/mytopic"}'
