Below is Configuration which I added to support the connection. But I am getting an exception on app startup only. I am able to connect with simple MongoDB but with Cosmos API I am getting the

You are using wrong method to create MongoRepository. You should use this one:
/**
* MongoRepository compatible with Amazon DocumentDB.
* <br/>
*
* Compound index on <code>commitProperties</code> isn't created.
* <br/><br/>
*
* See functional differences.
*/
public static MongoRepository mongoRepositoryWithDocumentDBCompatibility(MongoDatabase mongo, int cacheSize) {
return new MongoRepository(mongo, cacheSize, DOCUMENT_DB);
}
