I also faced same and followed below steps and it solved this issue.

1. npm install --save-dev @types/node in aws-mobile-ionic-sample\client folder
2. Adding "typeRoots" and "types" to "compilerOptions" in tsconfig.json like below { "compilerOptions": { "typeRoots": [ "node_modules/@types" ], "types": [ "node" ] } }
