Swagger throwing “Not a valid parameter definition”

Question

I am creating API documentation utilizing Swagger UI. I have many errors that say "Not a valid parameter definition" and I don't know why. Can anyone tell what or why this is happening? I include a section of the code and a picture with the line numbers and the error descriptions.

swagger example

#sys_application

/api/application/add:
  post:
    description: Adds specified application(s).
    parameters:

    - name: name
      in: body
      description: name of the application
      required: true
      type: string

    - name: appId
      in: body
      description: application id
      required: true
      type: string

    - name: icon
      in: body
      description: application icon
      required: true
      type: string

    - name: state
      in: body
      description: current state of the application
      required: true
      type: string

Answer 1

when you use in: body , the spec expects a schema element, such as:

name: user
in: body
schema:
  type: object
  properties:
    userId:
      type: string

If you're not using a body parameter, you are expected to use a primitive value, such as type: string .
