Overview

This node checks if the previous node returned an empty result. It is useful in workflows where you need to branch logic based on whether any data was received from a prior step. For example, it can be used to stop further processing if no data is available or to trigger alternative actions when the input is empty.

Use Case Examples

1. In a data processing workflow, use this node to verify if the previous node returned any records before proceeding with data transformation.
2. In an automation sequence, use this node to detect empty results and send a notification or log the event.

Output

JSON

• Result - Contains the original input data if it is not empty.
• IsEmpty - Contains an empty array if the input data is empty, indicating no data was received.

Troubleshooting

• If the node always outputs the 'IsEmpty' result, verify that the previous node is correctly configured and actually returns data.
• If the node does not behave as expected, ensure that the input data structure matches the expected format (an array of items with 'json' and optionally 'binary' properties).
