Hi @ManojK

The ~email file is the actual .xaml file name in your project. Before publishing UiPath checks the project for errors. That means that one of the activities in your workflow has validation errors. You could check the red and blue “bullets” to see exactly the activities that have errors.
Here is an example:

Hi Ovi,

Actually don’t see any validation errors. Please see attachment below.


Is there an “email” file in the Project panel?(left side of the screen) If so, please open it and check for validation errors.

When publishing it means that all the files in the project folder are archived.

Hi Ovi,

Thanks for help. No email related anything in the project panel.


Can you attach your project here?


Here it is.

Build XML.xaml (45.2 KB)

I get an error when publishing: “Project cannot be published. excel temp file has validation errors.”.
What other files do you have in your project folder?

I have these three items

I am also getting an error while trying to publish locally. Error - Invalid URI : URI is empty.


Error logs are :-
