I rewrote your OpenAPI spec. This version is valid:

swagger: '2.0'

info:
  title: Sample
  version: 1.0.0
  description: API for Sample

paths:
  '/customer/{customerId}/accountlist':
    get:
      responses:
        '200':
          description: ''
      parameters:
        - name: customerId
          in: path
          required: true
          type: string
      x-auth-type: None
      x-throttling-tier: Unlimited
      produces:
        - application/json
      x-scope: InternalUse

Some comments about your original version:

• The indenting was bad. For example the get: line needs to be indented from the preceding line. But perhaps that was just a copy & paste issue.

• The info object requires a version property.

• The customerId parameter included an allowMultiple property. I was seeing an error until I removed that.
