Graphql ServiceNow Integration

Graphql ServiceNow integration.
What is GraphQL?
GraphQL is a query language for API's and a runtime for fulfilling queries with existing data.
Instrictions to setting up GraphQL with Servicenow:
1. GraphQL API (sys_graphql_schema)
2. GraphQL Scripted Resolvers (sys_graphql_resolver)
3. GraphQL Resolver Mappings (sys_graphql_resolver_mapping)
4. End Point ([my-instance].service-now.com/api/now/graphql)
In this video, we also covered the Advantages/Disadvantages of GraphQL

Script used in the video:

1.GraphQL API:
schema {
query: Query
}
type Query {
getIncidentsByCallerID(calledID: ID!): [IncidentData]
}
type IncidentData{
number: DisplaybleString,
short_description: String
}
type DisplaybleString{
value: String,
display_value: String
}
_____________________________________________________________
2. GraphQL Scripted Resolver:
(function process(/*ResolverEnvironment*/ env) {
var grIncident = new GlideRecord('incident');
grIncident.addEncodedQuery("caller_id="+env.getArguments().calledID);
grIncident.query();
return grIncident;
})(env);

3. Syntax to Test:
{
x200273 {
agineo{
contactRequest(contactID: "6816f79cc0a8016401c5a33be04be441"){
short_description,
