Cannot run Amplify on Localstack

[mcsean-am]

I followed the instructions here: https://docs.localstack.cloud/user-guide/aws/amplify/

Running localstack at 3.2.0. Amplify is 12.10.1.

When I run amplify init --use-localstack true, it seems to work, however this shows up in the localstack logs:

2024-03-17T22:20:02.415  INFO --- [   asgi_gw_1] localstack.request.aws     : AWS amplify.ListApps => 200

2024-03-17T22:20:02.536  WARN --- [   asgi_gw_0] l.aws.protocol.serializer  : Response object BackendEnvironment contains a member which is not specified: appId

When I run amplify push --use-localstack true, I get:

✖ There was an error pulling the backend environment dev.
🛑 Stack with id amplify-amptest-dev-162002 does not exist
