Error "No such file or directory @ realpath_rec - /dev/disk/azure" starting CycleCloud Slurm cluster

I am attempting to set up a CycleCloud cluster using the tutorial found at https://learn.microsoft.com/en-us/training/paths/run-high-performance-computing-applications-azure/. While I have previously been able to follow that tutorial to set up a cluster, I am now getting an error when I reach Task 3: Configure and start an HPC cluster by using Azure CycleCloud in the exercise https://learn.microsoft.com/en-us/training/modules/azure-cyclecloud-high-performance-computing/5-exercise-create-cluster.

After starting the cluster, I get "Error configuring software". Showing details gives the following:

Errno::ENOENT: No such file or directory @ realpath_rec - /dev/disk/azure
