## AI-generated summary

A developer is encountering GraphQL errors when attempting to use the `validationCreate` mutation for Shopify Functions.

**The Query Structure:**
- Mutation attempts to create a validation with fields: `title`, `blockOnFailure`, `enable`, `functionId`, and `metafields`
- Variables include configuration data with namespace, key, type, and JSON value for function settings

**Errors Encountered:**
1. **Field 'enable' doesn't exist on type 'Validation'** - The `enable` field is not recognized in the Validation type
2. **Field 'functionId' doesn't exist on type 'Validation'** - Similar issue with `functionId` field
3. **Field 'metafields' selection mismatch** - The `metafields` field returns `MetafieldConnection` but has no selections (needs subfields like `{ edges { node { ... } } }`)

**Current Status:**
The discussion remains open with no responses yet. The developer has referenced the official Shopify documentation but the query structure appears to have type mismatches with the actual GraphQL schema.
