NEXTLY_SCHEMA_EXTEND_TARGET_UNKNOWN

Cause

A plugin extends an entity that neither the configuration, a plugin nor the Schema Builder declares.

A plugin's contributes.extend adds fields to an existing entity. The target it names is not a collection, single or field group in nextly.config.ts, in any plugin, or in the Schema Builder, which usually means a typo.

Fix

• Correct the target slug in the plugin's contributes.extend.
• Or create the entity it names, in nextly.config.ts or the Schema Builder.

Example

✗ Plugin "reviews" extends unknown entity "prodcuts".
  Why:  "prodcuts" is not a code-first or plugin collection, single or field group in the merged schema, and the Schema Builder has none by that slug.
  Next: Correct the target "prodcuts" in the plugin's `contributes.extend`, or create the entity it names.
