I am very new to GraphQl Magento. When I access the graphql url in my installation, following the below tutorial, it throws the below error. https://devdocs.magento.com/guides/v2.3/graphql/

Do I need to enable any modules, or set any configurations?

  "errors": [
      "message": "Syntax Error: Unexpected <EOF>",
      "extensions": {
        "category": "graphql"
      "locations": [
          "line": 4,
          "column": 35

I have this error too when i hit the graphql endpoint in my browser. After a debug attempt, it appears graphql expects a query to be passed. (the function to debug is \Magento\GraphQl\Controller\GraphQl::dispatch)

The quick way to get graphql running with examples you find around is to install GraphiQL, then a basic query that works at my end is:

        cmsPage(identifier: "no-route") {

For completeness, I have also tested Postman and I have it now working too (with more work than GraphiQL) by setting the following:

Header field Content-Type to be application/json Method to be POST


Another possible error might be because your endpoint is getting redirected and dropping the $_POST data.

Easy debug, just add to your index.php (might be the one in the /pub directory): var_dump($_POST) and try your query again. If the response comes back with an empty string, you know that your issue is that the body of the query is not getting passed to the Magento application.

Make sure the request is a POST and is going the secure_url of the website
