Problem Deserializing an Empty List

[trizzle21]

Hello! I'm having a small issue with a graphQL request that returns an empty list. I'm currently querying the Shopify Bulk Ingestion with a request payload that looks like:

query { 
     bulkOperationRunQuery (query:"long query") {
        userErrors { 
              field 
              message 
        } bulkOperation { 
              id 
             status 
        } 
    } 
} 

which has a response that looks like

{
  "data": {
    "bulkOperationRunQuery": {
      "bulkOperation": {
        "id": "gid:\/\/shopify\/BulkOperation\/720918",
        "status": "CREATED"
      },
      "userErrors": []
    }
  }
}

I have my objects that look like

public class BulkIngestionQueryOperation {

    @GraphQLArgument(name="query", type="String")
    private BulkOperationRunQuery bulkOperationRunQuery;

    public BulkOperationRunQuery getBulkOperationRunQuery() {
        return bulkOperationRunQuery;
    }

    public void setBulkOperationRunQuery(BulkOperationRunQuery bulkOperationRunQuery) {
        this.bulkOperationRunQuery = bulkOperationRunQuery;
    }
}

@GraphQLProperty(name="bulkOperationRunQuery", arguments={
        @GraphQLArgument(name="query")
})
public class BulkOperationRunQuery {
    private BulkOperation bulkOperation;
    private UserErrors userErrors;

    public BulkOperation getBulkOperation() {
        return bulkOperation;
    }

    public void setBulkOperation(BulkOperation bulkOperation) {
        this.bulkOperation = bulkOperation;
    }

    public UserErrors getUserErrors() {
        return userErrors;
    }

    public void setUserErrors(UserErrors userErrors) {
        this.userErrors = userErrors;
    }
}

public class UserErrors {
    private String message;
    private String field;

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public String getField() {
        return field;
    }

    public void setField(String field) {
        this.field = field;
    }

    public String toString() {
        return "error on " + field + " due to " + message;
    }
}

When I screw up the user fields and I get a UserError, my request deserializes correctly. However, when the request is successful, I get an empty list of UserErros to which I get the error,

'Cannot deserialize instance of `com.attentivemobile.bulk.ingestion.processor.model.graphql.UserErrors` out of START_ARRAY token
 at [Source: (String)"{"bulkOperationRunQuery":{"userErrors":[],"bulkOperation":{"id":"gid://shopify/BulkOperation/xxxxxxxxxxx","status":"CREATED"}}}"; line: 1, column: 40] 

Is there a feature or trick with that I'm not aware of or is this a known issue?

I know there are similar issues here, but they have a very different schema, doesn't involve an empty list and the solution involves moving the arguments to the nested object which is already the case here.

Thanks so much in advance!!
