Not a valid parameter definition Swagger.json

Question

I have this swagger definition

/memberdetails/Prospect:
    post:
      tags:
        - memberdetails
      summary: Create member details using member object.
      operationId: memberdetails.Prospect
      parameters:
        - name: authenticationkey
          in: formData
          required: true
          type: string
          format: JSON
        - name: member_object
          in: form
          required: true
          type: string
          format: JSON
      responses:
        '200':
          description: Request was successful
          schema:
            type: object
            properties:
              data:
                type: object
      deprecated: false

but it gives me below error

✖ Swagger Error Not a valid parameter definition Jump to line 6996 Details Object code: "ONE_OF_MISSING" params: Array [0] message: "Not a valid parameter definition" path: Array [5] schemaId: "http://swagger.io/v2/schema.json#" inner: Array [2] level: 900 type: "Swagger Error" description: "Not a valid parameter definition" lineNumber: 6996

Answer 1

Your second parameter has an invalid "in" value, it should be formData.

According to Swagger specification:

in: The location of the parameter. Possible values are "query", "header", "path", "formData" or "body".
