the sdk v1 has been deprecated, i got mine to work by changing the lambda code for ChimeAppInstanceLambda in the backend/template.yml to
ZipFile: >
"use strict";

          console.log("Create Chime SDK App Instance");
          var params = {

@stephen-tenorless the solution above should fix your deployment, however i am still running into dependency issues in the frontend with npm
