I'm try to add an rule in Azure DevOps so that when someone set an Severity, it automatically set the due date according to that Severity. Like this:
So the key is to get the date set based on today's date and then add a couple of days. When i try to do it with @Today (what is used in queries) I get an exception:
VS402809: @Today + 28 is an invalid value for field type DateTime. Change the field value and try again.
Someone an idea how to set this rule so it works?
