In my project I am using ApolloStudio for publishing my graphql queries,
Using rover script I published my new query and it reflected in the changeLogs also in the API schema. But when I tried it on the explorer it is showing an error

{
  "errors": [
    {
      "message": "Cannot query field "getApolloQuery" on type "Query".",
      "extensions": {
        "code": "GRAPHQL_VALIDATION_FAILED",
        "exception": {
          "stacktrace": [
            "GraphQLError: Cannot query field "getApolloQuery" on type "Query".",
            "    at Object.Field (/app/node_modules/graphql/validation/rules/FieldsOnCorrectTypeRule.js:48:31)",
            "    at Object.enter (/app/node_modules/graphql/language/visitor.js:323:29)",
            "    at Object.enter (/app/node_modules/graphql/utilities/TypeInfo.js:370:25)",

            "    at processTicksAndRejections (internal/process/task_queues.js:95:5)",
            "    at processHTTPRequest (/app/node_modules/apollo-server-core/src/runHttpQuery.ts:331:24)"
          ]
        },
        "HttpStatusCode": 500
      },
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ]
    }
  ]
}

getApolloQuery is the new query I published. Every this was working fine till last week, suddenly it happened like, the new queries and mutations are not accessible in the explorer. But it is reflected in the changelogs.

{
  "data": {
    "getApolloQuery": {
      "_id": "6641e71ec83611860bf04ace",
      "shipmentNumber": "TGLO-30062"
    }
  }
}

This is my expected response.
