I have a functionality to register a new user which works perfectly fine when I run the application in desktop modeler. I deployed the same in web modeler by below steps : Team -> Sync with Web modeler-> Click on "Open in Web modeler" -> Under "Publish" tab -> "Update" -> "View the app". I can see the UI part is updated in the app but on click of "Register" button gives error: "An error has occurred while handling the request." The same thing I do in desktop modeler, it works very well but not in web modeler. Please guide me with how do I get error logs in web modeler or what else needs to be done to solve the issue.
You could have a look at the app environment logs.
I would also make sure you are testing exactly the same way as when you run the app locally. Is it possible that your microflow is dependent on a certain data that is not setup in your sandbox environment but is locally?
