Check Empty

Check the previous node output is empty

Overview

This node checks if the output from the previous node is empty. It is useful in workflows where you need to branch logic based on whether the previous step produced any data. For example, you can use it to stop further processing if no data is available or to trigger alternative actions when data is present.

Use Case Examples

  1. In a data processing workflow, use this node to verify if the previous node returned any records before proceeding to data transformation steps.
  2. In an automation scenario, use this node to conditionally send notifications only if there is data to report.

Output

JSON

  • empty - Output when the previous node's data is empty
  • not empty - Output when the previous node's data is not empty

Troubleshooting

  • If the node always routes to the 'not empty' output, verify that the previous node is correctly producing data.
  • If the node always routes to the 'empty' output unexpectedly, check if the previous node's output is indeed empty or if the data structure has changed.
