I'm getting test failures locally related to Object.fromEntries @ kv-backend.js:116:

TypeError: Object.fromEntries is not a function
at KVBackend.getSecretManifestData (lib/backends/kv-backend.js:116:19)

Will wait and see if Travis fails too.

fromEntries requires node 12 if you are not using that :)

@Flydiverny, you're right; that was it. Was still on node 10 locally. Upgraded to 12 and everything passing. 🎉
