Convai Unreal plugin - Character self-interrupting - No responses

Unreal Engine Questions

I’m using the Convai plugin (version 4.0.0-beta. 11) in Unreal 5.5 with metahuman. For a while everything has been working fine until recently the character no longer responds to text nor audio inputs. When I attempt with text they look toward the player and my message appears in the widget, but no reply.

This is the output log when testing -

ConvaiPlayerLog: Started default audio capture

ConvaiSubsystemLog: Warning: OnDataPacketReceived: Unknown packet type ‘bot-turn-completed’.

It seems that the character is being interrupted before they are able to generate a response. However, push to talk is enabled so I’m unsure how this is being triggered.

Hello,

Welcome to the Convai Developer Forum!

Does it work when you send a text message?

3

Hi, no it doesn’t. My message will sometimes appear in the widget but the character doesn’t respond.

Please share all the logs.

I’ve shared the output log above. Can you please specify which logs you are requesting?

6

Don’t cut it, share all.

I tested both your character and your account and was not able to reproduce any issue.

If you are in a noisy environment, your microphone may be causing interruptions. I recommend muting your microphone and trying again, or making sure you are using push-to-talk mode.

If the issue continues, please try again in a new project. Also, please make sure you are not using a VPN or similar network tool.
