I’ve scheduled a site workflow. The workflow works if I start it manually. But once I set up a schedule for the workflow, it will notify by mail that the workflow failed to start and that it will retry later on.
The strange thing is, that even though it get the message that the workflow errored, I can see that the workflow is actually run ?!? The workflow runs through a list of items and for each item it checks if a Boolean is true or false. Based on the result an email is send out. So despite the fact that I receive a workflow error, the workflow is somehow executed.
Any idea what could cause this error?
