Failed to create ModelTargetObserver: DATABASE_LOAD_ERROR.

By Hiroshima on Wed, 09/07/2022 - 02:58

My Unity version is 2021.3.9f1

My Vuforia version is 10.9.3

I'm using webcam on my laptop as AR camera. But each time I click on "play", the scene showed the webcam view without any guide view lines and object recognition. There's an error goes:

Exception in callback: Failed to create ModelTargetObserver: DATABASE_LOAD_ERROR.

Can anyone help me to fix this error?

Thanks a lot!
