Can't build create-daml-app in 1.7

Questions

Steps to reproduce:

-- Edit daml.yaml so sdk-version: 1.7.0
daml build
daml codegen js .daml/dist/my-app-0.1.0.dar -o ui/daml.js
daml deploy --host localhost --port 6865
daml json-api --ledger-host localhost --ledger-port 6865 --http-port 7575 --address 0.0.0.0 --allow-insecure-tokens
cd ui/
export REACT_APP_LEDGER_ID=fabric-ledger
npm install
npm start

All building works up until npm start where I get the following error which I believe may be related to the recent api change in fetchByKey and similar functions:

Answered my own question, this issue can be resolved by manually setting your DAML_SDK_VERSION prior to running daml create-daml-app my-app. So in my example I would do: DAML_SDK_VERSION=1.7.0 daml create-daml-app my-app

This post shows how to specify it: Using old SDK version

You need to adjust both daml.yaml and package.json.
