I am using SharePoint 2013 foundation with 2010 workflows. Workflows keep failing. I get this error in the workflow history 'The workflow could not update the item, possibly because one or more columns for the item require a different type of information.The workflow operation failed because the workflow lookup found no matching item'
I tried to restart the workflows but I still get the same error. I also tried to publish workflows again but I still get the same error.
