Freshly generated library doesn't compile.

[SurferJeffAtGoogle]

I'm following instructions to generate a new library. The library is:
https://github.com/googleapis/nodejs-access-context-manager

When I run npm i in the root directory, I see this failure:

nodejs-access-context-manager$ npm i

@alexander-fenster would you mind taking a look into this (it's blocking coverage work)? 🙏🏻

Summer, can you please investigate what's going on here? Thank you!

@SurferJeffAtGoogle I'm not sure what the reason for this is, but it seems like we end up with an old version of google-gax when running the generation process. If one simply deletes node_modules and installs, the library behaves as you'd expect.

(these are fields that were added to gax a while back).
