Our API to list pickup points by location is always returning null  in the additionalInfo field. However, as this data normally comes from the logistics API then this data is present in the orderForm when placing an order at checkout.

Firstly, create a pickup point in the store admin and fill in the additional information field (pickup instructions and tags). After that, perform a call to our API which lists the pickup points by location and there you can see this field with null.

No workaround available.
