Describe the bug

I have an existing amplify app for my dev backend. That env works fine.

If I add a new 'test' amplify env using amplify env add. I cannot deploy it because it fails with the error:
Packaging lambda function failed with the error
Command failed with exit code 127: npm run-script amplify:testHostingFn
sh: tsc: command not found
> [email protected] amplify:testHostingFn
> cd amplify/backend/function/testHostingFn && tsc -p ./tsconfig.json && cd -

Expected behavior

The new test environment should be deployed

Reproduction steps

created next app -ts

created repo on code commit

pushed to code commit

initiated amplify

connected branch to amplify hosting

added amplify REST api & lambda express function

amplify push the BE

created app.ts & ts config etc according to https://docs.amplify.aws/cli/function/build-options/

amplify push

git commit and push - to kick off CICD

error during FE build cos of express already being declared as block scoped variable.

fix: exclude 'amplify' on main tsConfig.json

git commit and push - to kick off CICD
*** ALL Good up to now. env is deployed! ***

create test env following the insturctions: https://docs.amplify.aws/cli/teams/overview/#continuous-deployment-and-hosting

amplify add env -> test

amplify push

create git test branch and push

create hosting for test branch in amplify console.
Build fails: error:
