Ember 5.3.x has migrated from Ember-Inflector to '@ember-data/request-utils/string'.
After making the migration, ember-cli-mirage no longer recognizes the uncountable values set in the application initializer and Ember-Inflector must be explicitly called in mirage/config.js.
Separately when using Ember-Inflector and compiling the application with Fastboot, an error occurs:
const app = new Fastboot(...);
Error: Could not find module `ember-inflector` imported from `@ember-data/request-utils/deprecation-support`
