@Alex
I understand that you're encountering an issue with a bad request error due to an unexpected 'destinations' property in your JSON payload. To resolve this, you'll need to remove the 'destinations' property from your JSON object and ensure that the rest of your payload matches the expected schema for the API call you're trying to make.
If you need assistance with the correct structure of your JSON payload or with the specific API call you're working on, please provide me with more details, and I'll be happy to help you further.
