Error reverting deployment: Backup folder does not exist: /opt/FileMaker/FileMaker Server/Data/Backups/OttoFMS/deployment-backups/deploy-29/sub-deploy-33
I was able to replicate this, and its a somewhat interesting one. The issue (at least in my case) was that I sent an install deployment with a target folder that was not set in FileMaker. For Example, in my case I set the install options to install the file in the Additional Folder 1, which was not specified in FileMaker server. This causes OttoFMS to fail to find a folder path and attempt to install the file in no folder, which obviously fails. I can add a validation to ensure we find a folder, but its probably also an issue you can fix on your side if you’re hitting it for the same reason. Let me know if you have a similar setup in your deployment!
