Debugging

Inspect flow executions to find and fix issues.

Execution History

Click the History tab in the flow editor to see all past executions.

Each entry shows:

  • Status: finished (green), error (red), stopped (yellow)
  • Duration: total execution time
  • Timestamp: when it ran

Per-Block Results

Click an execution to expand it. Each block shows:

  • Status: OK, ERROR, or STOP
  • Duration: how long that block took
  • Outputs: all values produced by the block

This lets you trace exactly where data flows and where errors occur.

Test Mode

Click the play button in the flow editor to run a test execution with sample data. The results appear immediately in the history panel.

Common Issues

ProblemSolution
Block shows ERRORCheck the error message — usually a missing input or invalid data
Output is emptyVerify the input is connected (drag from previous block's output)
Flow doesn't triggerCheck that the flow is enabled and the connection is active
Vault value shows {{vault.KEY}}Re-save the flow so values are re-resolved, and verify the secret exists in the vault
HTTP request failsCheck URL, headers, and that the target isn't a private address

Helper Flow History

When ForEach calls a helper flow, each iteration creates a separate history entry in the helper flow. This lets you inspect what data was passed in each iteration.
