InvalidValueError: unexpected property "travelMode"

I'm getting the following error when I try to make a request while specifying the travelMode option:

(node:65354) UnhandledPromiseRejectionWarning: InvalidValueError: unexpected property "travelMode"

at Object.distanceMatrix (/Users/sacha/Dev/zensroom/node_modules/@google/maps/lib/index.js:55:25)

Looking at the code, it seems like the proper options is not:

travelMode: 'WALKING'

As specified in the docs, but instead:

mode: 'walking'

This should probably be documented/corrected somewhere?

You've mixed up the client-side JavaScript API with the server-side API that this library supports - https://developers.google.com/maps/documentation/distance-matrix/intro#optional-parameters

Oh ok, my bad! That's pretty confusing though, also the documentation doesn't make it very easy to locate the right API docs.
