ApiCallsChat.react(): Api endpoint is missing
Error: ""A JSONArray text must start with '[' at 1 [character 2 line 1]"
..... java.lang.IllegalArgumentException: No jsonNode given by the server! Check your Connection!
I checked the Api-Sourcecode. Im sure there is no test for channel.react(). But there are tests for chat.postMessage, chat.getMessage and some other methods. I can't find an endpoint in the code so I'm nearly shure the chat.react() endpoint is not implemented yet.
