I've just started working with flow, or trying to, with my on prem SharePoint 2013. I've setup the Gateway using my Farm Admin account and I'm now trying to create a flow with my regular account (has admin rights to lists i'm working on). After entering the site address the list filed is either showing a few list/libraries or an error code. one list is a calendar and the other is just a standard list.
My question is what are the requirements for getting flow to recognize SharePoint list and libraries on SP2013 on prem?
