### Describe the bug

I have a mono-repo, using NX and pnpm as my package manager. While one of my applications is a nextjs app, the one I want to deploy is a normal, client side rendered (no SSR) React application.

My Amplify build successfully completes with the following message:
```
2023-07-04T19:03:41.718Z [INFO]:
> NX Successfully ran target build for project [redacted] and 19 tasks it depends on
Nx read the output from the cache instead of running the command for 18 out of 20 tasks.
2023-07-04T19:03:41.821Z [INFO]: View logs and investigate cache misses at [redacted]
```

But then it does this:
```
2023-07-04T19:03:41.843Z [INFO]: Starting SSR Build...
2023-07-04T19:04:22.702Z [ERROR]: Serverless Error ----------------------------------------
```

I noticed that my platform is set to "Web dynamic" and my framework is set to "NextJS - SSR" and I've tried changing that via:

```
aws amplify update-app --app-id d2ymg159vgfgla --platform WEB --region us-west-1
```
and:
```
aws amplify update-branch --app-id d2ymg159vgfgla --branch-name main --framework 'none' --region us-west-1
```

and while I see it updated on my general settings page, it goes back to Web dynamic - NextJS - SSR every time I trigger a new build.

### Expected behavior

I would expect to use the generated static js files to host my client side rendered app, instead of trying to start up a server. AS a result I would expect my build to pass.

### Reproduction steps

1. trigger build
2. notice build breaks
