Aql internal error
description: IP Fabric describes the error message “Error: AQL: internal error - in index” that may occur and how to fix it.
Error: AQL: internal error – in index
When any error containing
Error: AQL: internal error - in index is
shown after any main action after upgrade (for example after Unloading
snapshot or starting Network discovery).
The database got corrupted (no worries all of your data are safely stored) and is necessary to run maintenance.
This can be done in Settings → Advanced → System in the main GUI. For more information see Schedule System Maintenance.
If this does not help, we recommend restarting ArangoDB process in
System Administration (port
8443) System Status and
running maintenance – see the previous step.
