The issue can be fixed by modifying the widget configuration in the control panel. Adding a section to the README to guide users on manual fixes could be a reasonable way to resolve it. Any thoughts?

Switched the paths in dashboard config and also the sequence in the array of EBS volumes added to the single-node construct. While also not a guarantee, it worked in the last 4 deployments.
