We are facing this issue in production intermittently.
In UAT it was all working fine and when testing in production also we dint face any error. When users started using the form workflow is giving the error "The Workflow Could Not Update The Item, Possibly Because One Or More Columns For The Item Require A Different Type Of Information".
In some blogs i read that we have to use "Commit pending changes" action before update item action. Even after using this we are still facing the issue. Please help us resolving this issue ASAP.
Seems its PROD performance issue, so try to check the workflow configuration and also try to add pause for few min's prior to "Commit pending changes" and after Update The Item action item.
