Copy new files from PC to Sharepoint

[cmathews]

I created a new flow from template to copy files from PC  to SharePoint using On-prem data gateway,   When a new files is created (test.txt), the files does appear properly in the SharePoint document library as test.txt.  However, when the file is overwritted or modified on the server, the same file is not overwritten in the SharePoint library.  What am i missing in my flow to update/overwrite the file within SharePoint?  Flow is below:

Hi @cmathews,

The issue is confirmed on my side, when I use the "Copy new files from your PC to SharePoint" built-in template of Microsoft Flow to create my flow, the issue is the same as you mentioned on my side.

I also have tried to create a flow from scratch and don't have the issue that you mentioned. My flow's configuration as below:

The flow works successfully as below:

Please consider take a try to create the flow from scratch, because, sometimes, there is something wrong with the built-in templates of Microsoft Flow. 

More details about creating a flow from scratch, please check the following article:
