  // Ember Data uses uuidv4 library to generate ids which relies on the crypto API which is no available in unsecure contexts
  // the suggested polyfill was added in 4.6.2 so until we upgrade we need to define our own id generation method
  // https://api.emberjs.com/ember-data/4.5/classes/IdentifierCache/methods/getOrCreateRecordIdentifier?anchor=getOrCreateRecordIdentifier
  // the uuid library was brought in to replace other usages of crypto in the app so it is safe to use in unsecure contexts
  // adapted from defaultGenerationMethod -- https://github.com/emberjs/data/blob/v4.5.0/packages/store/addon/-private/identifier-cache.ts#LL82-L94C2
