I have a nanoflow with a Retrieve Objects action which has the following XPath expression: [createdDate > '[%CurrentDateTime%] - 1 * [%SecondLength%]'] However, it generates Error Code CE0161 with the message: “Error(s) in XPath constraint”. It appears the [%SecondLength%] system constant is the culprit. If I create a microflow with the exact same XPath expression it works just fine. Is this a bug? What’s going on here?? Thanks.
