Get Value

Uncontrolled node

Overview

Extracts a value from an object, dictionary, or list using a specified path. This node supports nested property access via dot notation (e.g., user.name or items.0.value). If the specified path does not exist in the object, the node outputs the string 'undefined'.

The path input supports Handlebars-style template variables (e.g., {{variableName}}), allowing dynamic path construction using values from other nodes or workflow variables.

Inputs

Input	Type	Description	Default
Object	Data	The object, dictionary, or list to read from.	-
Path	Text	The path to the value using dot notation for nested properties (e.g., user.name, items.0.id). Supports template variables like {{key}}.	-

Outputs

Output	Type	Description
Value	Data	The extracted value at the specified path, or the string 'undefined' if the path does not exist.

Runtime Behavior

As an uncontrolled node, Get Value executes immediately whenever its inputs change. It does not require an event trigger to run. The node uses advanced dereferencing to navigate nested data structures, supporting both object properties and array indices in the path string.

If the path contains template variables (e.g., users.{{index}}.name), these are resolved first using available workflow variables and node inputs before accessing the object.

Example

Extracting a nested property:

• Object input: {"user": {"name": "Alice", "email": "alice@example.com"}}
• Path input: user.name
• Value output: "Alice"

Accessing array elements:

• Object input: [{"name": "Alice"}, {"name": "Bob"}]
• Path input: 1.name
• Value output: "Bob"

Using template variables in path:

• Object input: {"users": [{"id": "u1"}, {"id": "u2"}]}
• Path input: users.{{index}}.id (where index is a variable with value 0)
• Value output: "u1"
