HTTP 299 response causing error when attempting to parse the response

[babakontheweb]

We recently came across an error with our integration with this SDK where a POST to https://us-street.api.smarty.com/street-address responded with an unexpected status code HTTP 299. With the status code being a 2xx class, the SDK then attempted to parse the response only to fail with the following message and trace.

response.payload.map is not a function
TypeError: response.payload.map is not a function
    at assignResultsToLookups (util/sendBatch.js:30:20)
    at util/sendBatch.js:18:13
    at process.processTicksAndRejections (process/task_queues:95:5)

This was on version 5.1.1 of the SDK but reviewing the latest version of assignResultstoLookups the same issue should occur with the latest version.
