jsonapi-resources: wrong query

Processing by UsersController#show as JSON User Load (1.0ms) SELECT users.* FROM users WHERE users.id IS NULL ORDER BY users.id ASC LIMIT 1

wrong query is being issued for http://localhost:3000/users.json , any idea why this would happen ?

Using rails 5 with mysql2 output : { “errors”: [ { “title”: “Record not found”, “detail”: “The record identified by could not be found.”, “code”: “404”, “status”: “404” } ] }

but i have 50 users in my db
