Troubleshooting Error Code 14 in UE5

Hi,

I’ve seen a few posts relating to this issue. Is there a solution to this error? Is it related to what voice we use (Elevenlabs, Azure etc.)? Alternatively as a patch fix for now is there a way to detect the error within UE5 and reopen the level?

Hello Sophia,

You can try our latest update.

Just downloading the new release to test to see if the Error Code 14 is actually fixed. Have been using v 3.6.6 to be safe, however the emotion layers are not working as in no other emotion data is coming through other than Neutral: 1

Will report back after testing the new version.

Just tried the new version 3.6.8 Beta, and there is no response from the digital human. Looking at the log, ConvaiGRPCLog : Warning : OnStreamFinish: Status.ok():Not Ok | Debug Log: | Error message:upstream request timeout | Error Details: | Error Code:14 | Character ID:81b2b358-6cca-11f0-9210-42010a7be01f | Session ID:-1

Seems like a critical system error that the digital humans are not speaking at all anymore.

Quick update: Been working with the new plugin version 3.6.8 in Unreal Engine, the Error 14 still keeps showing up. The digital human is responding in big chunks of answers. Perhaps that’s what is causing the issue. In between statements, in the text widget, e see what the digital human is feeling,eg. *Takes a deep breath while holding a smile*.

Every so often, the lip sync breaks or the lips don’t move. With this new plugin should we be using the extra parameters we used previously? Or could that be the cause?

Is there any way to get the Error 14 issue resolved?

Could you please try this version?

Also noticed that when setting a User ID, after shutting off Unreal Engine and reopening, the User Id disappears and is not saved at all. How can we make the User IDs be preserved and saved and how can we add multiple User IDs to the Convai Base Player Blueprint.

Wanted to report this last month but forgot, just happened now so thought I’d let you know.

Tried adding this to the DefaultEngine.INI file (API Key Deleted for privacy purposes)

[/Script/Convai.ConvaiSettings]
API_Key=********************************
EnableNewActionSystem=True
ExtraParams=MinBufferDuration=3 AudioLipSyncRatio=0, EnableSync=0

The Error 13 is constantly interrupting the speech and the dialogue. This is most likely a time out issue on the Convai Server side. Can you please check this Kaan! Thanks!

This new error keep timing out the conversation regularly. It’s rather concerning. Earlier the Error would show up every now and then intermittently, but this new Error, it should on every conversation dialogue.

Thanks for the details. I’ll share the next update here.

Unable to load the project with the new plugin causes the Unreal Engine Project to crash and close. Perhaps an issue with the plugin itself.

Are you using 5.6?

Yes I am using the V5.6 plugin

Could you please share the logs? It’s working fine on our end without any crashes.

I am in the University and working on the work laptop and it seems that LiveCodingCosnole.exe gets initialized with the new plugin and that file is being blocked by the University Firewall. I have reached out to Central IT to unblock the file

That’s interesting, the update itself only includes a single line of code change, so it’s unlikely to be the cause. It’s possible your university’s IT team recently added new firewall or security policies.

Ok, managed to fire up the project and tried speaking with the digital human, straight away, Error 14 gets triggered.

The second time I tried, Error 13 is also getting triggered. Both logs are provided below.
