eas build --non-interactive requires (certain) interactions

[bensig]

Summary

When we run eas build --platform android --non-interactive - we still get an error about the metro.config.js that should be bypassed without a prompt. This has not been a problem when we run the build locally, but now that we are trying to automate the builds, it is becoming an blocker.

Error output

➜  bitcoin-libre git:(fix/metro-bundler) eas build --platform android --non-interactive --skip-project-configuration
✔ Linked to project @name/name (​https://expo.dev/accounts/name/projects/name​)
It looks like that you are using a custom metro.config.js that does not extend @expo/metro-config.
This can result in unexpected and hard to debug issues, like missing assets in the production bundle.
We recommend you to abort, fix the metro.config.js, and try again.

Reproducible demo or steps to reproduce from a blank project

We have tried to use the following metro.config.js - project builds fine with either, but both cause the error to appear even with --non-interactive specified on the eas build command:

module.exports = {
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
  },
  resolver: {
    sourceExts: ['jsx', 'js', 'ts', 'tsx'], //add here
  },
};

const {sourceExts} = require('metro-config/src/defaults/defaults');
const {getDefaultConfig, mergeConfig} = require('metro-config');

const cfg = async () => await getDefaultConfig();

module.exports = mergeConfig(cfg, {
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
  },
  resolver: {
    sourceExts: [...sourceExts, 'jsx', 'js', 'ts', 'tsx'],
  },
});
