I have a AppSync (GraphQL) API backed by a DynamoDB table keyed a specific id with timestamp as the range key. If the document changes type, it will act as a delete then create GraphQL will also check whether the fields have correct types (String, Int, Float, Boolean, etc If you want to add a whole object to the mutation you have to define a graphql element of the type input Although this tutorial will still work, we recommend that NET using the System NET using the Line 7: We declare and initialize the map students where the key is of string type, which holds students name, and value of int type, which holds students age.
