schema is invalid: data/required should be array

[rahuljain88]

Getting Error: schema is invalid: data/required should be array
at Ajv.validateSchema (/Users/rahulvageriya/.config/yarn/global/node_modules/ajv/lib/ajv.js:178:16)

When we used below JSON:

    - name: petId
      in: path
      required: true
      description: The id of the pet to retrieve
      type: string
      example: "1234567890"
  responses:
    '200':
      description: Expected response to a valid request 

But it worked fine when we use type or example under schema tag like below 👍

• name: petId
  in: path
  required: true
  description: The id of the pet to retrieve
  schema :
  type: string
  example: "1234567890"

Is it possible to use this type and example Tag without schema.?

The usage context is not clear - there is no code sample - but the problem is required: true - it should be defined on the object level in the schema as the list of required properties
