How it works Use the 'n8n' node to fetch the data of the failed execution Parse that data to find webhook nodes and extract the data of the one that was executed

Help me set up the n8n workflow "Access execution data from an error workflow" (https://n8n.io/workflows/2349). It uses: Code. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
