title: Google Datastore 1500 byte property limit for embedded entities
body: <p>According to: <a href="https://cloud.google.com/datastore/docs/concepts/entities#embedded_entity" rel="nofollow noreferrer">https://cloud.google.com/datastore/docs/concepts/entities#embedded_entity</a></p>
  
  <p>Setting the <code>excludeFromIndexes: true</code> 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.</p>
  
  <p>I am trying to write an embedded entity that has some properties that are longer than 1500 bytes and I'm getting an error:</p>
  
  <p><code>“Error: The value of property “additionalAttributes” is longer than 1500 bytes.    at /node_modules/grpc/src/node/src/client.js:434:17"</code></p>
  
  <p>Even though I'm setting the <code>excludeFromIndexes: true</code> (and I can see in the cloud console that the embedded entity is correctly being added without indexing) on the embedded entity. </p>
  
  <p>I see there is a known issue for this at: <a href="https://github.com/GoogleCloudPlatform/google-cloud-node/issues/1916" rel="nofollow noreferrer">https://github.com/GoogleCloudPlatform/google-cloud-node/issues/1916</a>. Though I don't see anything as far as a fix or workaround</p>
  
  <p>Any suggestions on what is causing this and how to fix/workaround?</p>
