WhatsApp Business Cloud: Send Template Message, Can't set variables of Template

Hi, I have the same problem, that when configuring the module “WhatsApp Business Cloud: Send Template Message”. I can not configure the variables present in the Template which then gives an error:

Here they found a workaround but I want to know if this will be fixed?

I have the same problem, the WhatsApp “Send a Template” module connects to the META API but does not mapp the variables already configured on the Message Models. I tried different ways to configure such variables but nothing works. Although the (META API) documentation refers to integer numbers as variables, like {{1}} ou {{2}} it only accepts names like {{agent_name}}.
