Convai Editor UE authentication issue

Unreal Engine Questions
1

Hello,

When I create new projects (VR template), the convai editor UI inside UE just loops on authentication and doesn’t ask for credentials. I don’t have the possibility anymore to add my convai API key to my project as it’s supposed to be automated now (that’s what it says at least in the API key field). My old projects still work fine as the API key has been set.

Steps followed: create new VR template, add convai in the plugins, restart project, upon restart a convai window pops up: “Welcome to Convai … Connect Convai Account” I press it → initializing convai → Authenticating… (and goes on forever)

I tried this on multiple desktops and my pc, same results (always logging out of every account)

I am working in UE5.5.4 with convai 4.0.0-beta.11

Hello,

Could you please share the logs?

I had to replace some links in the logs with … as it wouldn’t let me post otherwise

Additional note, all desktops and pc were on the same network

5

When you log in, does it get stuck on the “authenticating” screen? How are you logging in?

6

I am logged in in my epic games account. For the convai side: I’ve tried being logged in and out in the web browser, however inside of UE I never get logged in to my convai account. I just get this sequence:
“Welcome to Convai … Connect Convai Account” I press it → initializing convai → Authenticating…
And it stays forever stuck on Authenticating

7

For now, you can add your API Key by manually.

“{Project Name}\Config\DefaultEngine.ini”

Under [/Script/Convai.ConvaiSettings], you can add your API key.

8

Hello, I’ve been having this same problem with convai on UE 5.6. I put ApiKey={My ApiKey} under [/Script/Convai.ConvaiSettings] in DefaultEngine.ini using notepad and after saving and launching, it still prompts me to connect convai account. When I press the button, I get forever stuck on Authenticating

9

Which version of the Convai plugin are you using?

10

The version I’m using is 4.0.0-beta. 15

11

Hello, I have the same issue. I tried it on Unreal 5.3 and Unreal 5.5 and it still the same. I have tried to enter the APIKey in the ini file but still…

Here aare the logs when it blocks.

Thanks

Please download the file from this link.

Open the project root directory and create a folder named Plugins.

Then extract the downloaded file and drag the Convai folder into the Plugins folder.

13

Thank you,
I downloaded it and installed it (event removed the old one), and it’s stille the same…

Can I try something else?

For now, please use the following workaround.

If you are using the Marketplace version, open this file:

C:\Program Files\Epic Games\UE_5.X\Engine\Plugins\Marketplace\AIforNPCb346e0c968b9V8\Config\ConvaiEditorSettings.ini

If you installed the plugin from GitHub, open this file instead:

{}\Plugins\Convai-UnrealEngine-SDK-Dev\Config\ConvaiEditorSettings.ini

You can also check this path:

Plugins/Convai/Config/ConvaiEditorSettings.ini

In that file, find the following setting:

[ConvaiEditor]
editorUI.enabled=true

Change editorUI.enabled=true to editorUI.enabled=false.

Then open Unreal Engine.

Go to Project Settings > Convai and add your API key. You should then be able to continue using it this way.

15

This issue occurs in version 5.6 and earlier. It is related to the Chromium version used by Unreal Engine. We are currently looking for a solution. If you want you can use 5.7.

16

This workaround works!

Thank you !!

17

Issue should be fixed. Could you please try the normal flow?
