Error HRESULT E_FAIL has been returned from a call to a COM component when running inside a SQL Server Integration Services pipeline

[archanavedh]

Hi,

I am getting the below error while trying to execute the below code in script component in SSIS Package on server while it runs good on visual studio if execute manually.

Error:
Resize the Image:Error: System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e)
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.ProcessInput(Int32 inputID, PipelineBuffer buffer)
at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostProcessInput(IDTSManagedComponentWrapper100 wrapper, Int32 inputID, IDTSBuffer100 pDTSBuffer, IntPtr bufferWirePacket)

Code in Script component: In the below i am trying to resize the image whose length is greater than 400k to less than 400k

#region Help:  Using Integration Services Connnection Managers
/* Some types of connection managers can be used in this script component.  See the help topic
 * "Working with Connection Managers Programatically" for details.
 *
 * To use a connection manager in this script, first ensure that the connection manager has
 * been added to either the list of connection managers on the Connection Managers page of the
 * script component editor.  To add the connection manager, save this script, close this instance of
 * Visual Studio, and add the Connection Manager to the list.
 *
 * If the component needs to hold a connection open while processing rows, override the
 * AcquireConnections and ReleaseConnections methods.
 * 
 * Example of using an ADO.Net connection manager to acquire a SqlConnection:
 *  object rawConnection = Connections.SalesDB.AcquireConnection(transaction);
 *  SqlConnection salesDBConn = (SqlConnection)rawConnection;
 *
 * Example of using a File connection manager to acquire a file path:
 *  object rawConnection = Connections.Prices_zip.AcquireConnection(transaction);
 *  string filePath = (string)rawConnection;
 *
 * Example of releasing a connection manager:
 *  Connections.SalesDB.ReleaseConnection(rawConnection);

Interesting... The call stack stops short of showing any call into MagicScaler, so it's not clear what COM component the error is referring to. It's possible there's some CAS restrictions in place in SSIS that prevent unverifiable code, which would preclude running MagicScaler if so.

If I run the package removing this line of code
MagicImageProcessor.ProcessImage(msImage, msResize, settings); it gets executed successfully. The issue is with this method MagicImageProcessor.ProcessImage(msImage, msResize, settings);

Right, I have no reason to doubt the call to ProcessImage is failing. However, there is no indication whether the error is inside that method or whether SSIS has failed to load the type or invoke the call in the first place.

Your next troubleshooting step will need to be to get better error information from the SSIS host to determine where the failure is occurring.

We are using SQL Server 2012 and Windows Server 2008 R2 and I am not sure how to get better error information from SSIS
