Answer 1

Your controller code is validating the Model and returning the BadRequest: https://github.com/kajasumanie/calalogapi/blob/master/CalalogAPI/Controllers/BooksController.cs#L41
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
The error you are seeing is unrelated to Cosmos DB, whatever payload you are sending is not valid for the Catalog class.
That class is not available in your repo, so it's hard to say. You should check the payload versus the model class and verify the format and requirements are met.

Answer 2

I indicate the Id as Guid value. When try to add the order, I gave the id value as 1,2,3....
But Guid value I need to pass the Id value like 80000011-0005-fe00-b63f-84710c7967bb.
That is the problem .
