Root cause analysis revealed validator was looking at wrong path for
modes data. n8n stores modes at top level of properties, not nested
in typeOptions.
Changes:
- config-validator.ts: Changed from prop.typeOptions?.resourceLocator?.modes
to prop.modes (lines 273-310)
- property-extractor.ts: Added modes field to normalizeProperties to
capture mode definitions from n8n nodes
- Updated all test cases to match real n8n schema structure with modes
at property top level
- Rebuilt database with modes field
Results:
- 100% coverage: All 70 resourceLocator nodes now have modes defined
- Schema-based validation now ACTIVE (was being skipped before)
- False positive eliminated: Google Sheets "name" mode now validates
- Helpful error messages showing actual allowed modes from schema
Testing:
- All 33 unit tests pass
- Verified with n8n-mcp-tester: valid "name" mode passes, invalid modes
fail with clear error listing allowed options [list, url, id, name]
Fixes#304 (Google Sheets false positive)
Related to #306 (validator improvements)

This fixes a critical validation gap where AI agents could create invalid
configurations for nodes using resourceLocator properties (primarily AI model
nodes like OpenAI Chat Model v1.2+, Anthropic, Cohere, etc.).
Before this fix, AI agents could incorrectly pass a string value like:
model: "gpt-4o-mini"
Instead of the required object format:
model: { mode: "list", value: "gpt-4o-mini" }
These invalid configs would pass validation but fail at runtime in n8n.
Changes:
- Added resourceLocator type validation in config-validator.ts (lines 237-274)
- Validates value is an object with required 'mode' and 'value' properties
- Provides helpful error messages with exact fix suggestions
- Added 10 comprehensive test cases (100% passing)
- Updated version to 2.17.3
- Added CHANGELOG entry
Affected nodes: OpenAI Chat Model (v1.2+), Anthropic, Cohere, DeepSeek,
Groq, Mistral, OpenRouter, xAI Grok Chat Models, and embeddings nodes.
