Overview
The Example Node is a basic custom n8n node designed to demonstrate how to pass a string input through the workflow. It takes an input item, adds or updates a property called myString in the output JSON with the value provided by the user, and passes it along. This node is useful for testing, prototyping, or as a template for building more complex nodes.
Practical examples:
- Adding a static or dynamic string value to each item in your workflow.
- Testing how downstream nodes handle additional fields.
- Using as a starting point for custom node development.
Properties
| Name | Type | Meaning |
|---|---|---|
| My String | string | The description text (user-provided string that will be added to each item's output under the key myString). |
Output
Each output item will have its json field extended with a new property:
{
"myString": "<value of My String>"
}
If the input item already has other properties, they are preserved; only myString is added or updated.
If an error occurs and "Continue On Fail" is enabled, the output may also include:
{
"error": <error object>,
"pairedItem": <index>
}
This node does not output binary data.
Dependencies
- No external services or API keys required.
- No special n8n configuration or environment variables needed.
Troubleshooting
Common issues:
- If the "My String" property is left empty, the output will contain an empty string for
myString. - If an unexpected error occurs during processing and "Continue On Fail" is not enabled, the workflow will stop and display an error message.
Error messages:
- Errors thrown will typically relate to missing or invalid parameters. If "Continue On Fail" is enabled, errors are included in the output for the affected items.
- If you see a
NodeOperationError, check that all required properties are set correctly.
