Issue/Introduction

The 'Add Document' component works with small files, but throws an exception when files are greater than 2 MB.

Message :
System.Web.Services.Protocols.SoapException: There was an exception running the extensions specified in the config file. ---> Maximum request length exceeded.
at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)

Cause

The "Add Document" component's internal function relys on internal code in ProcessManager, thus also using the 'MaxRequestLength' property in Process Managers 'web.config'.  The actual project's 'web.config' does not govern attachment size referenced by the 'Add Document' component.

 

Resolution

Modify the 'MaxRequestLength' property in the ProcessManager 'web.config'.

This example sets the max file size to 50 MB:

<httpRuntime maxRequestLength="51200" executionTimeout="300"/>
