Cause

Cause type:
By design
Root Cause: The file \Widgets.Workflows\widget.execution.js had new functions added in ARA 12.0. This is a caching issue where the user’s browser is referencing the old file.

Environment

Resolution

1) Add <staticContent> configuration to the web.config files to skip caching: 

<system.webServer> 
.... 
<staticContent> 
<clientCache cacheControlMode="DisableCache" /> 
</staticContent> 
</system.webServer> 

2) Make sure all ARA instances in the F5 pool are updated to 12.0 

3) Restart the IIS Servers 

4) Clear browsers’ cache (Ctrl + Shift + Delete)
