stripPrefix not honoured when using host option in request

[bholbrook73]

{
    stripPrefix: '/api/v1',
    basePath: '/alpha',
    host: '1111111.execute-api.us-west-2.amazonaws.com',
}

Each endpoint is prefixed with /api/v1, which has been successfully stripped from the documentation, however, it's adding it to the end of host/basePath which provides an incorrect request destination.

Example Request Destination:
https://1111111.execute-api.us-west-2.amazonaws.com/alpha/api/v1/endpoint

Expected:
https://1111111.execute-api.us-west-2.amazonaws.com/alpha/endpoint
