Detect and Report Affected Workflows after n8n Upgrade

This n8n workflow is designed to identify workflows that may have been disrupted after upgrading to version 0.214.3, especially those with nodes that have multiple outputs, like ‘Switch’, ‘If’, and ‘Compare Datasets’. It utilizes a webhook trigger to start the process, queries all workflows via the n8n API, and analyzes their node connections to find potential issues caused by incorrect wiring in multi-output nodes. The workflow generates an HTML report listing affected workflows with links to inspect them individually, helping administrators quickly pinpoint and resolve wiring problems stemming from the version upgrade. This is particularly useful in maintaining workflow integrity and avoiding runtime errors in your automated processes.
