Example of throwing error for missing token via GraphQLResponse

[rex-remind101]

Hi, if the token is missing I'd like to throw an error by adding it to the errors payload in the response. This doesn't demonstrate that, do you have another example or could one be added please? Thank you.

Do it like this:

async fn index(
    schema: web::Data<TokenSchema>,
    req: HttpRequest,
    gql_request: GraphQLRequest,
) -> Result<GraphQLResponse> {
    let mut request = gql_request.into_inner();
    if let Some(token) = get_token_from_headers(req.headers()) {
        request = request.data(token);
    } else {
        return Err(actix_web::error::ErrorUnauthorized("unauthorized"));
    }
    Ok(schema.execute(request).await.into())
}
