I have made a (global) S3 bucket and copied the mobile-backend.template and the config-helper.template. Then I made another S3 bucket to hold the lambda-functions and copied the folder search/index.js, folder stream-handler/index.js, folder upload-note/index.js as well as files package.sh and upload.sh.

I created a cloud search domain, an api gateway and a cognito identity pool (federated) in my EU region.
I have checked and found all variables parameterized, except the constants.swift file which should not come into play before I start up the iOs demo?..

I started the cloud formation from the S3 bucket/mobile-backend.template.

These are the events in Test01 (name of the stack)

I launched the stack in Virginia successfully with the cloud formation template. The github explanation tells met to just copy the template and lambda functions in an S3 bucket and refer from my region..
to start the stack

What am I doing wrong.. thank you
