babel: {
      plugins: [ require.resolve('ember-auto-import/babel-plugin'), "transform-optional-chaining" ]
    }

      return formatterInstance.format(value, formatOptions?.unit ?? formatterOptions.unit);

@gedaiu please follow https://github.com/ember-fastboot/ember-cli-fastboot/issues/764#issuecomment-662424556 for a solution (TL;DR add node: current to config/targets.js).

Upstream fix is part of latest v3 beta, see #770 for details

@SergeAstapov the upstream fix will only apply in the case that you install ember-cli-fastboot using ember install. It uses the default blueprint to apply node: current to your targets file.

There will be a follow-on feature where we will error if there is not node version defined in your targets file so the issue will be crystal clear to end-users that the need to add it 👍
