Our organization is attempting to use the React 19 beta for our internal tools to get ahead of the upgrade for production. However, we encountered a blocking issue with react-relay.
The loadQuery method uses __SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED which was renamed in React 19 to __CLIENT_INTERNALS_DO_NOT_USE_OR_WARN_USERS_THEY_CANNOT_UPGRADE.
This results in runtime and build issues when attempting to use react-relay, like this one:
Attempted import error: 'SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED' is not exported from 'react' (imported as 'r').
