Testing sending events to EventStore with Elixir

eventstore_test.ex

iex(1)> event = [%{"eventId" => "fbf4a1a1-b4a3-4dfe-a01f-ec52c34e16e4", "eventType" => "event-type", "data" => %{"a" => "1"}}]

   "eventType" => "event-type"}]

iex(2)> {:ok, json_event} = JSX.encode event
{:ok,
 "[{\"data\":{\"a\":\"1\"},\"eventId\":\"fbf4a1a1-b4a3-4dfe-a01f-ec52c34e16e4\",\"eventType\":\"event-type\"}]"}

defmodule EventStore do
  
  def store_event(stream, event_type, event_data) do

    {:ok, data} = JSX.encode event_data

    HTTPoison.request(:post, "http://localhost:2113/streams/#{stream}", data, [{"Content-Type","application/json"},{"ES-EventType",event_type},{"ES-EventId",UUID.uuid1}])

end

trying to leave comments doesn't work!

oh now it does it was 404'ing.

1. what else is in the log .... e.g. around that.

2. You should be able to reproduce this in curl rather trivially?

I was able to solve my issue by posting the EventType and EventId in the headers rather then in the JSON data.

then you should change your content type to application/json

http://docs.geteventstore.com/http-api/3.1.0-pre/writing-to-a-stream/

btw your content type should be application/vnd.eventstore.events+json in your original example ...

Ah yes it should. Thanks. I am going to be working this into a CQRS example I am playing with in Elixir. https://github.com/ddamko/elixir_cqrs_es

I do continually get this error after running ./run-node.sh on my linux machine
