According to: <https://cloud.google.com/datastore/docs/concepts/entities#embedded_entity>

Setting the `excludeFromIndexes: true` on an embedded entity should remove both it and its properties from being indexed and should therefore allow the properties of that embedded entity to be greater than 1500 bytes.

I am trying to write an embedded entity that has some properties that are longer than 1500 bytes and I'm getting an error:

`“Error: The value of property “additionalAttributes” is longer than 1500 bytes. at /node_modules/grpc/src/node/src/client.js:434:17"`

Even though I'm setting the `excludeFromIndexes: true` (and I can see in the cloud console that the embedded entity is correctly being added without indexing) on the embedded entity. 

I see there is a known issue for this at: <https://github.com/GoogleCloudPlatform/google-cloud-node/issues/1916>. Though I don't see anything as far as a fix or workaround

Any suggestions on what is causing this and how to fix/workaround?
