Short summary

Seg fault caused by null pointer/missing ssl cert

What happened?

When connecting to convai on a meta quest with an unreal engine v5.5 built app, the app will crash due to a seg fault in the connection logic in v4. This seems to be caused by a null pointer either from a missing ssl cert or the inability to open a file correctly on the quest or android.

Steps to reproduce

create a unreal engine project using convai v4 and package it for android and meta quest
install on meta quest
launch the app and connect to convai

Hello, just checking in to see if there has been any updates on this issue?

4

There is no update yet.

Unfortunately, this issue has been difficult to reproduce consistently, so our team is still investigating it.

5

could it possibly be related to this error? It’s something I encountered when upgrading and resolved on my own but could be related? my fix for it was to inject some gradle settings using an apl xml file but maybe in doing so a specific version of something is being replaced?

here is a ue project with the bare minimum that let’s me make a build and launch, it then promptly crashes when the convai connection is attempted in loading.

The issue has been resolved, and the fix will be included in our next update.

Please stay tuned for the upcoming release.

Could you please try again?
