Unable to create datacontext object for IndexedDB provider using JayData Framework 1.3.1

Unable to create datacontext object for IndexedDB provider using JayData
Framework 1.3.1

I'm unable to create datacontext object for IndexedDb provider using
Jaydata framework 1.3.1 and getting "FailedProvider fallback failed!"
message for $todo.context.onReady().
What is the syntax to define dataprovider for IndexedDB? I found below
code in Jaydata documentation, but it doesn't work because "
$data.types.storageProviders" API doesn't showing up "indexedDb" class in
it.
$news.context = new $news.Types.NewsContext({ name: "indexedDb",
databaseName: "NewsReader", dbCreation:
$data.types.storageProviders.indexedDb.DbCreationType.DropStoreIfOlderVersion,
version: 1 });
