@ember-data/debug/data-adapter.js: Cannot read properties of undefined (reading 'env') about data

[runspired]

on current canary you need to install @warp-drive/build-config and setConfig within ember-cli-build (see test apps for examples). This is something we're working to find a way to avoid being a breaking change before shipping to stable, but the old style of config will be deprecated and this new style is going to be a required thing for apps to do.

Thanks for explanation! I installed @warp-drive/build-config and changed the ember-cli-build.js and now everything is building successfully again. Now I have to dig through a lot of changes because of the changes in the Schema service.

FTR, I have installed the 5.4.0-alpha.73 versions of the different packages and changed the ember-cli-build.js as follows

module.exports = async function (defaults) {
  const { setConfig } = await import('@warp-drive/build-config');

  .....

  setConfig(app, __dirname, {
    compatWith: process.env.EMBER_DATA_FULL_COMPAT ? '99.0' : null,
  });

  ....

};

Mind the async and await.
