**Moved from GitHub [dgraph-js/24](https://github.com/dgraph-io/dgraph-js/issues/24)**

_Posted by_ [jeffkhull](https://github.com/jeffkhull):

Versions:  
dgraph-js: 1.1.0  
dgraph: 1.0.2 or 1.0.3

This error happens when trying to perform any query against the database, after upgrading from grpc 1.8.4 to grpc 1.9. I downgraded to 1.8.4 and the problem goes away. Would be interested to know if anyone else can reproduce this.

Fixed in the latest beta. I will release a stable version soon. You can install the beta using `npm install dgraph-js@1.1.1-beta.2`.
