OS Name/Version: Debian 10.7.0
Product Name/Version: v2.4.6.4
Problem Description:
I am receiving an error when I try to start AMPINSTMGR.
[Error] Failed to read instance data; System.NullReferenceException: Object reference not set to and instance of an object at InstanceManagerPlugin.LocalInstanceManager.GetLocalInstances (System.String AlternateDefsPath) [0x00lf5] in <5c2c29a9f8lc460584925e6a5140ec35>:0
I’ve reviewed the instances.jason and AMPConfig.conf but dont see any objects directly relating to this error. Everything in the instances.json points to the correct location to find the AMPConfig.conf file.
This may be due to an unexpected power outage. Reviewed log file for 10/5 and last version check was 8am which was after outage. Fairly sure all system clocks are in alignment, made some changes to files and correct time stamp was recorded. No logs recorded since.
Actions taken to resolve so far:
I’ve made sure my drives are mounted and readable
Replaced the ADS01 instance folder with a recent backup
Replaced the instances.json file with the most recent .bak file
I’m at a loss here, any help or guidance is greatly appreciated.
Update
I performed an install, got the web instance back. Posting my console from reinstall. Just stops at the last waiting statement.
Any advice to get the instances back or just try piecing the files one by one?

2nd Update
After reinstallation and creation of a new instances.json file the web server would open, I decided to try using a .bak file that was a few revisions earlier. This worked and restored my AMP to a known good state prior to my adding of a new datastore. I must have a discrepancy with a file location of the 2nd datastore which is causing ampinstmgr to return the error and refuse to launch. During the setup of the additional drive I must have not fully had the mounting location and auto mount configured. This was evident when reviewing drives in the GUI. I edited my fstab to what I thought was correct and everything looked ok but still did not launch.
Now I’m off to work on the configuring of the directory structure. Hope this helps someone in the future.
