I am not having a good update cycle here….
Can you post a debug log? And would check your buddy handles are correct? Did add some extra logging here as per github issue and possible something is up with that - should only happen when buddy handle fails though.
Edit:
Suggests that the sql connection to iMsg database has never been connected.
There should be messaging well before this.
2nd Thought:
It may relate to the File permissions - Indigo 2023.2 is a new version and new Files - so you may need to update security permissions.
This screen here the IndigoPluginHost and the IndigoServer need to be updated to the new 2023.2 Indigo files versions.
Indigo client not needed so do not need to update the Indigo 7.4 app here to Indigo 2023.2 app
