The script fails at the line set source-ip $(vdom) because the predefined metadata variable $(vdom) resolves to the name of the Virtual Domain (e.g., "root" or "AGEUSR"), which is a string. The set source-ip command requires a valid IP address, not a string name. The "object unrecognized" error occurs because the FortiGate CLI parser does not recognize the VDOM name as a valid IP address.

To resolve this, the administrator must create a custom metadata variable (e.g., netflow-source-ip) and assign the correct source IP address value to this variable for each specific VDOM. The script should then be modified to use this new variable, for example: set source-ip $(netflow-source-ip).

A. A permissions issue would likely generate a "permission denied" error, not an "object unrecognized" error related to an invalid value in a script.

B. Running the script on the device database bypasses the policy package model and does not fix the underlying script error, which is the incorrect use of the $(vdom) variable.

D. Normalized interfaces are used to abstract physical interface names for use in firewall policies within a policy package, and are not relevant to system-level CLI configurations like NetFlow.

Section: Scripts

Subsection: Using variables in scripts.

This section details the use of both predefined variables and custom metadata variables (referred to as Device VDOM variables). It explains that $(vdom) resolves to the VDOM name. It also describes how to create custom variables and assign device-specific or VDOM-specific values

which is the required solution to provide a valid IP address in this scenario. (p. 268-270)
