"content": "# ⚠️ When and how to use this workflow\n\nIf you previously upgraded to n8n version `0.214.3`, some of your workflows might have accidentally been re-wired in the wrong way. This affected nodes which have more than 1 output, such as `If`, `Switch`, and `Compare Datasets`.\n\nThis workflow helps you identify potentially affected workflows and nodes that you should check.\n\n**❗️Please ensure to run this workflow as the instance owner❗️**\n\n1. Configure the \"Get all workflows\" node to use your n8n API key. (You can find/create your API key under \"Settings > n8n API\")\n2. If you have community nodes installed that have more than 1 output, add them to the constant `MULTI_OUTPUT_NODES` in the \"Parse potentially affected workflows\" code node.\n3. Activate the workflow\n4. Visit `{YOUR_INSTANCE_URL}/webhooks/affected-workflows` from your browser\n5. The report will list potentially affected workflows/nodes.\n 1. The square brackets after the workflow name list the potentially affected nodes\n 2. Inspect each reported workflow individually (you can click on a row to open it in a new tab)\n 3. **Verify that the correct outbound connectors are used to connect subsequent nodes.**"
