Describe the bug

With certain data model settings, I encounter a type error Type instantiation is excessively deep and possibly infinite. which causes my build to fail. I've set up a repo with a model that experiences this failure here: https://github.com/johnpc/amplify-demo-data-type-infinite (see repro steps).

Expected behavior

Build succeeds without type error

Reproduction steps

git clone https://github.com/johnpc/amplify-demo-data-type-infinite
cd amplify-demo-data-type-infinite
npm install
npm run build
# build will fail with "Type instantiation is excessively deep and possibly infinite."

Closing since the fix has been merged in.

I had talked to @iartemiev about this, but the perf improvements in #104 did not resolve my issue.

[johnpc]

actually false alarm, this is fixed in the latest @beta

[anthonyhoegberg]
