Unable to get authentication for 'getUser' query with @isAuth directive

[EdwardEddyEd]

When following the tutorial, I was able to execute the 'createUser' mutation successfully, but was unable to continue after the 'getUser' query. I made sure to include the bearer token in the 'HTTP HEADERS' tab at the bottom of the graphql playground. Unfortunately, I was given the following output:

{
  "data": {
    "getUser": null
  },
  "errors": [
    {
      "message": "User not authenticated",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "getUser"
      ],
      "extensions": {
        "code": "INTERNAL_SERVER_ERROR",
        "exception": {
          "stacktrace": [
            "Error: User not authenticated",
            "    at field.resolve (/Users/edward/Documents/WebFiles/mainDirectory/node_graphql_apollo_template/src/graphql/directives/auth.directive.ts:27:15)",

            "    at <anonymous>",
            "    at process._tickDomainCallback (internal/process/next_tick.js:229:7)"
          ]
        }
      }
    }
  ]
}

I tried logging through auth.directive.ts and reading docs about SchemaDirectiveVisitors but couldn't fix the issue. Is there something that I'm missing in trying to resolve this error? Thanks!
