I'm trying to use a Site workflow to run a List Workflow on a particular item in a document library by using the Call Web Service - StartWorkflow action. I receive the following error message: Error returned from server: <soap:Fault xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>soap:Server</faultcode><faultstring>Server was unable to process request. ---> Value does not fall within the expected range.</faultstring>
I have double-checked that the file URL works (I purposely input an incorrect URL and received a "Could not find the file to start workflow on" error instead), so it would appear that the issue is in invoking the workflow on the item.
The workflow exists and is associated with the library. The workflow can be fired manually on an item in the library.
Any ideas on what could be causing this?
