How can I alter payment terms in Shopify Flow?

I am trying to update the payment terms on orders with a certain tag and are in the unpaid status. However, I am receiving this error, see attached pictures. Any help would be appreciated.

You are getting that error because the customer that is provided from the Order can be “null” and that action does not allow potentially null Customers. We have a potential solution in the works for this that will allow actions to accept a resource that can be null.
