data at the root level is invalid. line 1 for SSIS

问题

I need to use VS2015 with SQL Server 2012 in my SSIS project.

When I changed Deployment Target Server Version from SQL Server 2016 to SQL Server 2012 I get following error.

OData V4.

Stack Trace:

Data at the root level is invalid. Line 1, position 1. (System.Xml)

Program Location:

at System.Xml.XmlTextReaderImpl.Throw(Exception e) at System.Xml.XmlTextReaderImpl.Throw(String res, String arg) at System.Xml.XmlTextReaderImpl.ParseRootLevelWhitespace() at System.Xml.XmlTextReaderImpl.ParseDocumentContent() at System.Xml.XmlTextReaderImpl.Read() at Microsoft.SqlServer.IntegrationServices.OData.UI.ODataConnectionManagerForm.TestConnectionMiddle(Object callback)

回答1:

The endpoint https‍://localhost:44354/odata is not returning any XML.

You need to correct issues with that endpoint or switch to a different one.
