This exception can encapsulate many different types of errors. To determine the specific error always look at the StatusCode property. Some common codes you may get when creating a Document are:
|StatusCode||Reason for exception|
|404||NotFound - This means the resource you tried to read did not exist.|
|429||TooManyRequests - This means you have exceeded the number of request units per second.|
// Reads a Database resource where database_id is the ID property of the Database resource you wish to read. Database database = this.cosmosClient.GetDatabase(database_id); DatabaseResponse response = await database.ReadAsync();
Doing a read of a resource is the most efficient way to get a resource from the Database. If you know the resource's ID, do a read instead of a query by ID.
