error code 600 retrieving from a datalink server

[jmillar]

Hi all;

 We're using a datalink server as a quick way to expose data.  I have the following data source defined:

var kiPMDataSource = new kendo.data.DataSource({
    type: "everlive",
    transport: {
        typeName: "KI"
    },
    schema: {
        model: {
            id: "Id"
        }
    },
    serverSorting: true,
    sort: {
        field: "Id",
        dir: "asc"
    },
    serverFiltering: true,
    filter: {
        logic: 'and',
        filters: [
            {field: 'Id',operator: 'eq',value: new Date('October 28 2015')},
            {field: 'report_group',operator: 'eq',value: 'PM'}
        ]
    }
});

However when I launch app in AppBuilder, using the debugger, I can see the read request for this datasource yields a Status 400/Bad Response.  The Request looks like:

Accept:application/json, text/javascript, */*; q=0.01
User-Agent:Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A537a Safari/419.3
X-Everlive-Filter:{"Id":"2015-10-28T04:00:00.000Z","report_group":"PM"}
X-Everlive-Sort:{"Id":1}

​The response I get back is:

{"message":"Data Link Server Error: Filter cannot have multiple or no children.","errorCode":660}

 Thanks,

Jason

Hello Jason,

Indeed, this filter is supported in types from a Data Connector.

I do apologize if this is causing any inconvenience, but perhaps the issue would be fixed with updating the Data Link server installation on your premises.

A link to the download and the documentation for the update procedure are available here.

I hope that this helps. Let us know should you have any further questions.

Hi Anton;

I replaced the existing folder with the new DataLink server download.  Now my data link server isn't returning anything.  

 Thanks,

Jason

Hi Anton;

 A few more details -- it seems that the new datalink server is responding OK when I run it from a command prompt.  However, we had been running it as a Windows service.  The Windows service fails to stay running -- I have tried removing and reinstalling the service entry, but it's still the same behaviour.

 

Thanks,

Jason
