Unable to Delete Cloud Anchor #390

Closed sele98 closed 1 year ago

sele98 commented 1 year ago

Description

Anchors are created and located without issues, but when I want to delete an anchor, I get this error: "The specified spatial anchor is already associated with a different store". I followed steps from Tutorial and implemented Create, Locate and Delete methods in my project accordingly. I was able to find reference of this error happening when deleting an Anchor from OnCloudAnchorLocated callback - #61, also when trying to update an existing Anchor - #58. In my case, delete action is initiated on a button click.

Steps to reproduce the issue

  1. Open Azure Session
  2. Create/Load Azure Spatial Anchor
  3. Close Azure Session
  4. Open Azure Session
  5. Delete Azure Spatial Anchor (code below)
  6. OnError event is invoked and Azure Spatial Anchor is not deleted.

Expected behavior

Anchor should be deleted from Azure Service

I'm sure cloudAnchor is not null, Log next line shows correct Id.

Hi @sele98, can you share the log? Also, does the basic sample in this repo work properly? I get something like this when it is working:

Thank you @darax for a quick response! I tried this sample and it works as it should. I updated package versions in my project to match ones in the sample, but it still gives me the same error. Here's the Unity log.

Okay, I think I see the issue. I'm guessing that the GameObject anchor being passed in to DeleteAzureAnchor is from the previous session. Instead, you need to get a new reference to the anchor in the new session that is being created. One way to go about this would be:

 CloudSpatialAnchor csa = await _cloudManager.Session.GetAnchorPropertiesAsync("anchor-guid-goes-here");
await _cloudManager.DeleteAnchorAsync(csa);

That did the trick. Thank you very much!
