Heroku Buildpack error

[omi-akif]

Hello. I wanted to try out the Chat Services of ParlAI by typing the command:

python parlai/chat_service/services/messenger/run.py --config-path parlai/chat_service/tasks/chatbot/config.yml

I encounter an error.

The error message:

You are going to allow people on Facebook to be agents in ParlAI. During this process, Internet connection is required, and you should turn off your computer's auto-sleep feature.

Could it be that the ParlAI is creating a heroku app without mentioning the build packs? Is there any way around for this problem?

[klshuster]

have you set up your heroku credentials?

[omi-akif]

Yes @klshuster, I have done that. I tried to follow this guide of ParlAI chat service. I tried to follow the steps mentioned. No Webhook URL was posted. I am also logged in heroku-cli.

[klshuster]

Maybe CC @JackUrb who might know why heroku is not working here. Have you searched elsewhere for this issue? It may not be related to ParlAI specifically?

[JackUrb]

Hm this is bizarre. Honestly I haven't worked on the chat service setup in a long time, but over in Mephisto we've specified this sort of thing in our deployed servers by defining a Procfile. Perhaps the same is required here?

[omi-akif]

Hey @klshuster . I believe this could be something related to the server setup code. I am currently trying to debug this.

Hey @JackUrb . I am trying to look a way on how to rewrite the script of server.py to see if I can find some good results. Could you please keep the issue open for one or two weeks so that I can manage to find a solution for this?

[klshuster]

Yes, feel free to come back and update us when you find something!
