InvalidOperationException: SpatialAnchorManager is improperly configured.

[sana2024]

I have azure spatial anchor with unity and MRTK (Introduction to the Multi-user capabilities tutorials) the session starts find but when I try to change between scenes it crashes

I have a scene for login and the azure spatial anchor scene I login and jump to the ASA scene just fine and I am also able to start the session and locate anchors but when I go back to signup scene it throws this error: InvalidOperationException: Anchor manager has no subsystem

and when I open the ASA scene again and click start session it crashes and shows this error: InvalidOperationException: SpatialAnchorManager is improperly configured.

is there a way I can change scenes without this issue?? note: I stop the session when the scene changes using cloudManager.DestroySession()

I'm using iPhone 11 AR foundation 4.1.1

@darax would you be available to help here? thanks! (cc @pamistel )

Hi @sana2024, When ASA raises this error in most cases it will also log what it is missing before throwing the exception. There is a good chance that whatever is missing was destroyed when switching scenes. To get around this there are a couple of choices: a) you can use do not destroy on load. A script that calls this API should be attached to the root of the object with all of the ARfoundation scene setup. b) you can make a prefab that will be instantiated with all of the ARFoundation prerequisites, like the ARSessionOrigin and the ARAnchorManager.

@sana2024 - I'm going to close this item, but please reach out if you have any follow-up questions, thanks!

I got the same error. This is what I was doing wrong: When I closed Unity, my keys got deleted, so go to the GameObject that contains SpatialAnchorManager script and re-enter your keys.
