Mulesoft Dataweave: can import Strings but not Dates

I have a Mule application project in which I'm able to import dw::core::Strings but unable to import dw::core::Dates. To reduce the problem to a small example, I have a Transform Message block which sets an output variable to this:

%dw 2.0
import * from dw::core::Strings
import * from dw::core::Dates
output application/json
---
leftPad('Code', 9, 'M')

When I try to debug this application, execution fails at that block with this error:

""Script '%dw 2.0
import * from dw::core::Strings
import * from dw::core::Dates
output application/json
---
leftPad('Code', 9, 'M')
 ' has errors: 
    Unable to resolve module with identifier dw::core::Dates. at 3 : 3" evaluating expression: "%dw 2.0
import * from dw::core::Strings
import * from dw::core::Dates
output application/json
---
leftPad('Code', 9, 'M')
"."

If I remove the line about importing dw::core::Dates, then the block executes with no error and is able to call the leftPad method imported from Strings.

I know I don't have any calls to Dates methods in this example. I will add those once I'm able to import dw::core::Dates without an error. How do I get it to resolve and import the Dates module?

I'm using Anypoint Studio version 7.9.0 with Mule Server 4.3.0 EE. Thank you.

Solution

  • dw::core::Dates was introduced in Mule 4.4 with DataWeave 2.4.0. It is not present in Mule 4.3 which includes DataWeave 2.3.0. The only solution is to upgrade the version of Mule.
