Total timeout of API google.datastore.v1.Datastore exceeded 60000 milliseconds

Hello, we are getting this error from nodejs-datastore-sdk in our clusters in production from time to time:
```
Error: Total timeout of API google.datastore.v1.Datastore exceeded 60000 milliseconds before any response was received.
```
We are having this error for more than one year and no one seems to know what's going on, can you guys at least enlighten us on what could be possibly happening???

1) Is this a client library issue or a product issue?
Yes, it looks like a bug into nodejs-datastore-sdk

2) Did someone already solve this?
