@yuyaito I am looking into WebSocket related issues, can you please provide more info on this issue as mentioned by @germanattanasio

[yuyaito]

Thank you for your confirmation.
Steps to reproduce as below.

1. Modify ruby SDK as below.
   ibm_watson/websocket/speech_to_text_websocket_listener.rb l71

# before
EM.stop_event_loop
# after
EM.stop_event_loop if EM.present? && EM.connection_count <= 1

ibm_watson/websocket/speech_to_text_websocket_listener.rb l78

# before
EM&.reactor_thread&.join
# after
# EM&.reactor_thread&.join

ibm_watson/websocket/speech_to_text_websocket_listener.rb l158

# before
@bytes_sent += chunk.size
@client.send(chunk.bytes)
@client.send({ "action" => "stop" }.to_json) if final
@timer.cancel if @timer.respond_to?(:cancel) && final
# after
begin
  @bytes_sent += chunk.size
  @client.send(chunk.bytes)
  @client.send({ "action" => "stop" }.to_json) if final
  @timer.cancel if @timer.respond_to?(:cancel) && final
rescue => error
  Rails.logger.error("send_chunk_error: #{error.message}, #{error.backtrace_locations.inspect}")
  @callback.on_error(error: error)
end

2. Open one or more websocket connection with Watson STT, and run real-time recognition several tens of minutes.

3. (sorry don't know the cause) occured its typeerror.

Hi @yuyaito, We are investigating issues related to STT WebSocket and we are planning to have a patch out by the end of this month, and we are tracking work here.

[mamoonraja]

@yuyaito What's the reason behind modifying the SDK code as you mentioned in #50 (comment).

[EikiWakamatsu]

I will reply instead of Mr. yuyaito

I modified the library to allow multiple connections for Issue #39 .

#EM&.reactor_thread&.join

This error now occurs.

[mamoonraja]

@EikiWakamatsu Why are you commenting the line out? Please try this example snippet.

@mamoonraja
When run according to the example, the connection was successful.
Thank you.
