Graphql Update Syntax issue with App sync - amazon-web-services

Question

I am not familiar with appsync's syntax with graphql. I am trying to update one of my entities using app sync. I used Amazon's option to automatically allocate resources and connect them to DynamoDB. Here is my entity:
type Property {
id: ID!
address: String!
listedDate: AWSDate!
notes: String
homeType: String!
tenantName: String!
ownerName: String!
leaseExpDate: AWSDate!
}
Inside of my mutations, I have this:
type Mutation {
updateProperty(input: UpdatePropertyInput!): Property
}
Along with this input:
input UpdatePropertyInput {
id: ID!
address: String
listedDate: AWSDate
notes: String
homeType: String
tenantName: String
ownerName: String
leaseExpDate: AWSDate
}
Here is my attempt at the mutation to update the given property:
mutation updateProperty {
updateProperty(input: UpdatePropertyInput(id: 'myID')) {
address: String!
}
}
The closest implementation that I found in the appsync's docs can be found here.

Input objects are constructed using brackets like below:
mutation updateProperty {
updateProperty(input: {
id: "myID",
address: "myAddress"
}) {
address
}
}
Here is some additional documentation on input objects can be found here:
