I am very new to all of this but I have pushed my way through and have been able to create a few workflows. However, I have an issue that I have not see before. I am using a Data Gateway as my SharePoint site is on-premise. It's a fairly simple workflow that should trigger when an item is modified. However, I am getting this error that says I am not able to perform that operation with an On-Premise data gateway. If that is true then how do I trigger the workflow when an item is modified?
