Echo

The Echo effect writes whatever value it receives to the flow execution log. It does not affect your stream or viewers in any way -- it is purely a debugging tool. Connect it to any node's output to inspect the data flowing through your flow at that point.

This is especially helpful when building or troubleshooting a flow. If a downstream node isn't behaving as expected, attach an Echo effect to the suspect output to see exactly what value it is producing.

Inputs

NameTypeDescription
ValueanyThe value to log. Can be a string, number, boolean, or object.

Example

You have a flow that builds a chat message from several pieces of data, but the final message looks wrong. Attach an Echo effect to each intermediate node's output to see the values at every step. Once you find where things go off track, fix the issue and remove the Echo nodes.
