## Linear ticket https://linear.app/chatwoot/issue/CW-6834/billing-upgrade-didnt-work ## Description A `customer.subscription.updated` Stripe webhook for account 76162 returned 200 OK but did not persist the new `subscribed_quantity`. Root cause: a race condition between the webhook handler and `increment_response_usage` (Captain usage counter), both doing read-modify-write on the `custom_attributes` JSONB column. The webhook wrote `quantity: 6`, then a concurrent `save` from `increment_response_usage` overwrote the entire hash with stale data — restoring `quantity: 5`. Fix: use atomic `jsonb_set` so usage counter updates only touch the single key they care about, instead of rewriting the whole `custom_attributes` hash. `increment_custom_attribute` also performs the increment in SQL, making concurrent increments correct as well. ## Type of change - [x] Bug fix (non-breaking change which fixes an issue) ## How Has This Been Tested? - New regression spec in `handle_stripe_event_service_spec.rb` that simulates concurrent webhook + `increment_response_usage` and asserts both `subscribed_quantity` and `captain_responses_usage` survive - Existing account, billing, captain, and topup specs all pass locally ## Checklist: - [x] My code follows the style guidelines of this project - [x] I have performed a self-review of my code - [x] I have commented on my code, particularly in hard-to-understand areas - [ ] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] Any dependent changes have been merged and published in downstream modules |
