Bug Description

Hi! I've decided to use Robyn together with strawberry-graphql but is seems it not working properly. Robyn has a problem with rendering the answer from the standard introspection query. With the following code:

app = robyn.Robyn(__file__)


@app.post("/graphql")
async def handle_api_request(request: robyn.Request) -> robyn.jsonify:
    body = request.json()
    query = body["query"]
    variables = body.get("variables")
    context = {}
    root_value = body.get("root_value", None)
    operation_name = body.get("operation_name", None)
    data = await schema.execute(
        query,
        variables,
        context,
        root_value,
        operation_name,
    )
    return robyn.jsonify({
        "data": (data.data),
        **({"errors": data.errors} if data.errors else {}),
        **({"extensions": data.extensions} if data.extensions else {}),
    })


@app.get("/graphql", const=True)
async def handle_api_playground_request(request: robyn.Request):
    return {
        "description": strawberry.utils.graphiql.get_graphiql_html(),
        "headers": {
            "Content-Type": "text/html"
        }
    }

I going to always get the following response:

ERROR:strawberry.execution:Syntax Error: Unexpected <EOF>.
