Hey I am having issue with my windows and quest 3 application. I am using Convai plugin version 3.6.9 hotfix-1. We have metahumans in our project I have 3 types of characters in my project. At the start the of the project around 1-1.5 months ago the response speed is good but now 2 weeks back all of a sudden I am getting very delayed response around 5-8 seconds delay.
On quest3 my application crashes many times when the character tries to speak for the first time. Crash also happens on windows but very rare. I often get “response timeout” and often it breaks the flow while receiving the audio from user with error “Error→Outputlog→ResponseFailed“.
Character ID’s:
06adb25e-8820-11f0-b4bf-42010a7be01f
a19aee7c-8950-11f0-942d-42010a7be01f

Here are the convai and unreal logs. In here I don’t have the crash as I mention it happens sometimes, So whenever it will happen I will share the logs for that as well. But in here I am getting delayed response.
Hey any update on this?
Please make sure you are sharing the correct logs. The logs you attached do not contain any errors.
Can you please take a look at these logs. These aren’t for crashing it’s for delayed response and timeout errors.

Delayed response for around 10 seconds and when I quit play it totally freezes the editor for some 10-20 seconds.
Hey any update on the shared details?
I’ve checked your character on our side and couldn’t see any issues. We also tested it and were not able to reproduce the 10 second response delay you’re seeing.
Please try the following:
-
Test the same character in the Convai Playground on convai.com and see if you can reproduce the delay there.
-
Try switching to a different LLM and voice combination and test again.
-
From your project it looks like you have some custom logic added in Unreal, which might be contributing to the editor freeze.
And just as a small note: to remove the Convai logo, you need to be on an appropriate paid plan.

Can you please look into this?, In these logs you can find the crash.
Also I am facing another issue sometime convai says /response “Slash response“ and [Previous company] “Bracket previous company bracket“ how can I resolve that so it will never come again?
Project_20250721.log (246.0 KB)
Please create a new project. Do not modify any Convai plugin BPs. Import your character and build/package it for the Android platform. Because we are unable to reproduce these crash issues.
For the second issue, did you upload any Knowledge Bank file?
Yes I have uploaded the knowledge bank and connected the file as well.
Okay but in my project I have modified some BP’s that comes with convai sample project. Let me check in a blank project.
This is regarding your KB file. Please make sure that your KB file does not mislead the LLM and that it is in English.

Can you please look at these crashlogs.
Are you testing it in an empty level?
