Scope/Environment

SDL Tridion Sites 9.x, SDL Web 8.5 Content Porter

Symptoms/Context

Using SDL Tridion Sites 9.x/SDL Web 8.5 and Content Porter leads to an error trying to import large files into the system. From the import log:

[Critical] System.ServiceModel.CommunicationException: An error (The request was aborted: The request was canceled.) occurred while transmitting data over the HTTP channel. ---> System.Net.WebException: The request was aborted: The request was canceled.
at System.Net.HttpWebRequest.GetResponse()

Made all the changes as discussed here:

Content Porter - Tridion.ContentManager.ImportExport.Packaging.OpenPackageException on large file

Resolution

On the system where you have installed the ContentPorter client installed, open the file system.servicemodel.bindings.config. The out of the box StreamUpload bindings are as such:

<!-- ImportExport_StreamUpload binding -->
<binding name="ImportExport_streamUpload_basicHttpBinding_http" maxReceivedMessageSize="2147483648" transferMode="StreamedRequest" messageEncoding="Mtom" receiveTimeout="00:30:00" allowCookies="true">
<security mode="None" />
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" />
</binding>
<binding name="ImportExport_streamUpload_basicHttpBinding_http_basicAuth" maxReceivedMessageSize="2147483648" transferMode="StreamedRequest" messageEncoding="Mtom" receiveTimeout="00:30:00" allowCookies="true">
<security mode="None" />
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" />
</binding>
<binding name="ImportExport_streamUpload_basicHttpBinding_https" maxReceivedMessageSize="2147483648" transferMode="StreamedRequest" messageEncoding="Mtom" receiveTimeout="00:30:00" allowCookies="true">
<security mode="Transport" />
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" />
</binding>
<binding name="ImportExport_streamUpload_basicHttpBinding_https_basicAuth" maxReceivedMessageSize="2147483648" transferMode="StreamedRequest" messageEncoding="Mtom" receiveTimeout="00:30:00" allowCookies="true">
<security mode="Transport" />
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" />
</binding>

This needs to be changed so that it includes a sendTimeout as such:

<!-- ImportExport_StreamUpload binding -->
<binding name="ImportExport_streamUpload_basicHttpBinding_http" maxReceivedMessageSize="2147483648" transferMode="StreamedRequest" messageEncoding="Mtom" receiveTimeout="00:30:00" sendTimeout="00:30:00" allowCookies="true">
<security mode="None" />
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" />
</binding>
<binding name="ImportExport_streamUpload_basicHttpBinding_http_basicAuth" maxReceivedMessageSize="2147483648" transferMode="StreamedRequest" messageEncoding="Mtom" receiveTimeout="00:30:00" sendTimeout="00:30:00" allowCookies="true">
<security mode="None" />
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" />
</binding>
<binding name="ImportExport_streamUpload_basicHttpBinding_https" maxReceivedMessageSize="2147483648" transferMode="StreamedRequest" messageEncoding="Mtom" receiveTimeout="00:30:00" sendTimeout="00:30:00" allowCookies="true">
<security mode="Transport" />
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" />
</binding>
<binding name="ImportExport_streamUpload_basicHttpBinding_https_basicAuth" maxReceivedMessageSize="2147483648" transferMode="StreamedRequest" messageEncoding="Mtom" receiveTimeout="00:30:00" sendTimeout="00:30:00" allowCookies="true">
<security mode="Transport" />
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" />
</binding>

Root Cause

The StreamUpload binding in the Content Porter client configuration does not have the necessary sendTimeout values in place.
