Issue accessing RealSense Device

[BettaDayz]

Hi all!

Im currently trying to use bonsai with the RealSense package, using the most simple workflow (i.e. RealSense Device as source, then accessing color and depth stream), but I get an error when I try to start the workflow. I have copy-pasted the code below:

Bonsai.WorkflowRuntimeException: Error calling 'rs_get_device' with context:0000000021CD9290, index:0. out of range value for argument "index" ---> RealSense.Net.RealSenseException: Error calling 'rs_get_device' with context:0000000021CD9290, index:0. out of range value for argument "index"
at RealSense.Net.Native.NativeHelper.ThrowExceptionForRsError(IntPtr error)
at RealSense.Net.DeviceCollection.get_Item(Int32 index)
at Bonsai.RealSense.RealSenseDevice.b__0()
at System.Reactive.Linq.ObservableImpl.Defer`1._.Run()
--- End of inner exception stack trace ---

Is there anything I can do to mitigate this error? I am using a D435 RealSense camera.

Hi @BettaDayz can you try the pre-release version 0.3 of the package? Uninstall the released version 0.2.0 first, and then using the package manager, check the box that says Include prerelease, and search for RealSense with the package source - Bonsai Packages. It should bring up a package with the official red bonsai logo and version 0.3.0-build3440 (Prerelease). If it works, can you give an update here? It seems the last update on this topic was from https://groups.google.com/g/bonsai-users/c/IGVoEvjqjUw/m/lzF6mDHZAgAJ and I'm not sure if the prerelease version fixes the issue.
