TanStack DB error 17 (key=1, collectionId="todos"): https://tanstack.com/db/latest/docs/errors#error-17

TanStack DB error 17 (key=1, collectionId="todos"): https://tanstack.com/db/latest/docs/errors#error-17

Multiple instances of @tanstack/db detected!

This causes transaction context to be lost because each instance maintains its own transaction stack.

Common causes:
1. Different versions of @tanstack/db installed
2. Incompatible peer dependency versions in packages
3. Module resolution issues in bundler configuration

To fix:
1. Check installed versions: npm list @tanstack/db (or pnpm/yarn list)
2. Force a single version using package manager overrides:
   - npm: "overrides" in package.json
   - pnpm: "pnpm.overrides" in package.json
   - yarn: "resolutions" in package.json
3. Clear node_modules and lockfile, then reinstall

To temporarily disable this check (not recommended):
Set environment variable: TANSTACK_DB_DISABLE_DUP_CHECK=1

Cannot insert document with key "123" from sync because it already exists in the collection "collection-1"

Cannot insert document with key "key-1" from sync because it already exists in the collection "collection-1". This collection uses a custom getKey with .distinct(). The .distinct() operator deduplicates by the ENTIRE selected object (standard SQL behavior), but your custom getKey extracts only a subset of fields. This causes multiple distinct rows (with different values in non-key fields) to receive the same key. To fix this, either: (1) ensure your SELECT only includes fields that uniquely identify each row, (2) use .groupBy() with min()/max() aggregates to select one value per group, or (3) remove the custom getKey to use the default key behavior.

Joined queries can produce multiple rows with the same key when relationships are not 1:1.
