(I didn’t want to resurrect that thread, but it’s the same error.)

When running a query I get the following error.

  Error: 2 UNKNOWN: : while converting to subgraph: while filling args: strconv.ParseInt: parsing "": invalid syntax
      at Object.exports.createStatusError (/home/node/app/node_modules/grpc/src/common.js:91:15)
      at Object.onReceiveStatus (/home/node/app/node_modules/grpc/src/client_interceptors.js:1209:28)
      at InterceptingListener._callNext (/home/node/app/node_modules/grpc/src/client_interceptors.js:568:42)
      at InterceptingListener.onReceiveStatus (/home/node/app/node_modules/grpc/src/client_interceptors.js:618:8)
      at callback (/home/node/app/node_modules/grpc/src/client_interceptors.js:847:24) {
    locations: [ [Object] ],
    path: [ 'userList' ]
  }

My query is

query items($firstPager_first: int, $userPager_first: int) {
  var (func: type(User)) {
    main as uid
  }

  totalCount (func: uid(main)) {
    count(uid)
  }

  first (func: uid(main), orderasc: <username>, first: $firstPager_first) {
    uid
  }

  last (func: uid(main), orderdesc: <username>, first: $firstPager_first) {
    uid
  }

  items (func: uid(main), orderasc: <username>, first: $userPager_first) {
    uid
    username
    status
    dgraph.type
    email
  }
}

$firstPager_first and $userPager_first are 1 and 20 respectively.

If I run the query in Ratel, I don’t see any errors.

If I dig into grpc, it looks like the error is part of the dgraph response.

Okay, I figured it out. Dgraph-js only accepts strings or string objects as arguments. I am unsure whether this issue is replicated in other clients.
