BUILDER_SLUG_COLLISION

Cause

An entity in ui-schema.json has the slug of a collection in nextly.config.ts.

nextly migrate:check reads the entities the Schema Builder saved in ui-schema.json beside those in nextly.config.ts, and a slug may be declared in only one of them. The Why line lists each slug both files declare.

Fix

• Remove each slug listed from one of the two files, or rename it in one of them.
• Run nextly migrate:check again.

Example

✗ An entity is defined in both `nextly.config.ts` and `ui-schema.json`.
  Why:  slug 'posts' is defined in both nextly.config.ts and ui-schema.json
  Next: Remove each slug listed from one of the two files, or rename it in one of them, then run the command again.
