Pass parameter to Visual Composer (VC) from workflow

Hi,

We created a Visual Composer application which we would like to call from a workflow.

Our Visual Composer application expects an input value called WI_ID.

Our task is TS99700043 and its visualization contains DYNPARAM: wi_id=${item.externalId}.

But the value is not passed on to the VC application

Do you know how to fix this issue?

Thanks,

Eva
