Problem

Groovy's Date objects no longer works in 7.7 September 2020 Release, though it worked previously. For example, the following script will fail:

import com.vordel.trace.Trace;

def invoke(msg) {
    Trace.debug(new Date().format("ddMMyyyy"));
    return true;
}

Causing an error similar to this:

ERROR   01/Oct/2020:00:00:00.000 [0000:000000000000000000000000] Filter that caused failure: Scripting Language

Resolution

The methods for java.util.Date are now in the groovy-dateutil module, which isn’t included by default. Accordingly, you can fix this problem by copying the groovy-dateutil JAR from the Groovy Maven repository into /apigateway/ext/lib and restarting the affected instances.

Issue will be fixed in November 2020 release.
