Description

Fastify-swagger & fastify-multipart setup with request.file() logic in validation

Doesn't see on UI select file option, on swagger 2.0.0 version it suggests to send binary, which is not ux oriented
When I set body instead of requestBody in schema, UI is present but generates bad request response

Expected Behavior

UI should be presented and works good with fastify-multipart
