Expo-linking cannot read scheme from Constants.manifest

I’m receiving the following runtime error after building with eas:

Constants.manifest is null because the embedded app.config could not be read. Ensure that you have installed the expo-constants build scripts if you need to read from Constants.manifest

I’m in a managed workflow.

I have an app.json file but not an app.config file.

I’m not sure what the expo-constants build scripts are referring to
