Description

I tried to create an EdgeFunction with cdk, but the following error occurred because backend.createStack does not allow you to set the region.

Unable to build the Amplify backend definition.

Caused By: Error: stacks which use EdgeFunctions must have an explicitly set region
at EdgeFunction.createCrossRegionFunction (/Users/suzumuradaichi/github/MiracleLinkMaker/node_modules/aws-cdk-lib/aws-cloudfront/lib/experimental/edge-function.js:1:7079)

Resolution: Check your backend definition in the amplify folder for syntax and type errors.
