Failed to delete router.

Error message

Failed to delete router.

What it means

Failure indicator from the DELETE /model-routers/:id endpoint: ModelRouter.delete returned a falsy result, meaning the router row could not be removed (typically it no longer exists), and the endpoint responds 400 with success:false.

Solutions

1. Check server logs for the database error.
2. Verify the router exists and no dependent rules block deletion, then retry.

When it happens

Trigger: Thrown at server/endpoints/modelRouter.js:101 when the library encounters an invalid state.
