How to Covert Graphql schema to JSON schema?

We are using App Services to access MongoDB. Currently, App service requires JSON schema but we have Graphql schema so we are converting it to JSON schema using GitHub - charlypoly/graphql-to-json-schema: GraphQL Schema to JSON Schema while we are deploying the converted JSON schema, we are getting the following error:

Here is our Graphql schema:

type Query {
user: User
}
type User {
name: String!
profile: Profile!
email: String!
role: Role!
}
type Profile {
name: String!
age: Int!
}
enum Role {
USER
ADMIN
}

Here is the converted JSON schema:

{
“$schema”: “http://json-schema.org/draft-06/schema#”,
“properties”: {
“Query”: {
“type”: “object”,
“properties”: {
“user”: {

},

},

},

“description”: “The String scalar type represents textual data, represented as UTF-8 character sequences. The String type is most often used by GraphQL to represent free-form human-readable text.”
},
“Profile”: {

“type”: “object”,

},

},
“required”:
}
},
“required”: [“name”, “age”]
},
“Int”: {
“type”: “number”,
“title”: “Int”,
“description”: “The Int scalar type represents non-fractional signed whole numeric values. Int can represent values between -(2^31) and 2^31 - 1.”
},
“Role”: {
“type”: “string”,
“anyOf”: [{
“enum”: [“USER”],
“title”: “USER”
}, {
“enum”: [“ADMIN”],
“title”: “ADMIN”
}]
},
“Boolean”: {
“type”: “boolean”,
“title”: “Boolean”,
“description”: “The Boolean scalar type represents true or false.”
}
}
}
Can you help me to resolve it or provide the way to use Graphql schema for App Services?
