Unable to build Workflow Management MTAR

In Business Application Studio, while building the Workflow Management MTA project with a Task UI5 view, using the latest Build Tool (1.2.27) the system ends with the following error:

Hi pedromiguelfernandes,

In reproduce steps, which 'Dev Space' should be selected to create a new Workflow Management MTA on SAP Business App Studio ?

Thanks

Hi Yutao,

I had this issue in two different landscapes, different subaccounts and different spaces. At this point, I don't know if the problem is in the generator, the build tool or just a simple case of PEBCAK.

Thank you for the support,
Pedro
