There is no need to parse the query param again manually. connexion also takes care of injecting the 100 default value from from openapi spec for you. as for offset handling, the offset should be calculated using `offset * limit`. The connection implementation uses `query.offset(offset).limit(limit)`, which is a bug. You can port the `test_should_get_list_variables` test to connection test suite and checkout the test error. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
