Solution
Refresh the FYI web app as follows:

1. Navigate away from the page that is showing the error by selecting a different menu option from the top navigation.
2. Refresh the FYI app. Refer to Checking the latest version of the FYI web app.
3. Select the function or document again that was giving the error (for example, go to Automations and  open the relevant Automation Process again.
