Changes

AsyncManagementClient registers _enforce_custom_domain_whitelist as a request event hook on an httpx.AsyncClient when custom_domain is set. httpx.AsyncClient awaits its hooks, and that function is synchronous, so every request fails with TypeError: object NoneType can't be used in 'await' expression.

This change adds _enforce_custom_domain_whitelist_async, a coroutine that calls the existing whitelist check, and registers it on the async client. ManagementClient keeps the sync hook.

• Functions added: _enforce_custom_domain_whitelist_async (private)
• Methods changed: AsyncManagementClient.__init__ (no signature change)
• New tests send requests through httpx.MockTransport for both clients and check that the header is kept on /api/v2/users/{id} and removed on /api/v2/clients/{id}.

• httpx event hooks: httpx.AsyncClient hooks must be async functions.

Testing

poetry run pytest tests/management/test_management_client.py -k request_enforces_whitelist: 2 passed. Without the source change, test_async_request_enforces_whitelist fails with the TypeError above. poetry run pytest: 724 passed, 4 skipped.
