n8n v1 Upgrade Helper: Pinpoint Affected Expressions
detail.loadingPreview
Seamlessly transition to n8n v1 by identifying expressions potentially impacted by breaking changes. This helper workflow scans all your active automations, pinpointing exact locations where specific date/time expressions (`beginningOf`, `endOfMonth`, `minus`, `plus`) are used, allowing for targeted review and adjustments.
About This Workflow
Upgrading to n8n v1 introduces powerful new features, but some changes, particularly around expression handling for date and time operations, can affect existing workflows. This essential helper workflow acts as your personal n8n auditor. Upon execution, it intelligently queries all your active workflows, diving deep into node parameters to detect the presence of specific expression extensions known to be impacted by v1 updates. It provides a detailed report, outlining the workflowName, nodeName, and parameterName for every detected instance, enabling you to proactively review and adapt your automations, ensuring a smooth and error-free transition to the latest n8n version.
Key Features
- Comprehensive Workflow Scan: Automatically retrieves and analyzes all your active n8n workflows for potential v1 compatibility issues.
- Targeted Expression Detection: Specifically identifies usages of
beginningOf,endOfMonth,minus, andplusdate/time expression extensions affected by n8n v1 changes. - Detailed Location Reporting: Provides precise details including the workflow name, node name, and parameter name for each identified affected expression.
- Proactive Issue Identification: Helps you find and address potential breaking changes before they cause workflow failures post-upgrade.
- Simplified Upgrade Process: Streamlines your n8n v1 migration by highlighting areas requiring manual review and adjustment.
How To Use
- Set up n8n API Credentials: Ensure you have an active n8n API credential configured in your n8n instance, which the 'n8n' node will use to access your workflows.
- Import the Workflow: Import this JSON snippet into your n8n instance as a new workflow.
- Activate the Workflow (Optional): While this is a helper, you might want to activate it if you plan to run it repeatedly, though it functions perfectly well when inactive and manually executed.
- Execute Manually: Click the 'Execute Workflow' button in the n8n UI.
- Review the Output: Examine the output of the 'Find params with affected expressions' node. It will provide a list of objects, each indicating a
workflowName,nodeName, andparameterNamewhere an affected expression was found. - Inspect and Update: Navigate to the identified workflows and nodes. Manually review the parameters using the specified expressions and make any necessary adjustments to ensure v1 compatibility.
