Intent

An exploded object is represented by its properties. If none is required, required: true on the wrapper cannot make any query key mandatory.

See it fail

- in: query
  name: filter
  required: true
  style: form
  explode: true
  schema:
    type: object
    properties:
      status: { type: string }

Fix it

Add required: [status] inside the schema, or make the parameter optional.
