Cannot get example to work

[neverfox]

No matter what I try as a query, I get the following error in devtools (react.min.js):

Uncaught TypeError: Cannot read property 'getQueryType' of undefined

[dsifford]

@neverfox Can you provide an example of some of the queries you are trying?

[neverfox]

Well, I'm a total newbie when it comes to graphQL, but I was trying things from the examples like:

query UsersQuery {
  users {
    name
  }
}

I assume that if was just badly formed, I'd get an error inside of graphiql, but it's just failing at the source code level somehow. Do you know of a query that you know should work that I could try?

[dsifford]

Hm.. I see what you mean..

The GraphiQL instance is not getting access to the database on my end. Tried to spin up the example on my end and no dice either.

@neverfox are you able to open up the "Doc" sidebar and see the schema? If not, you probably have the same issue.

I'd usually troubleshoot, but I'm strapped for time and I'm not familiar with koa.

[neverfox]

Nope, no schema.

Make sure that MongoDB is running.

[dsifford]

@tothandras Not sure that's the issue. MongoDB runs as a service on my machine (Ubuntu Wily) and I have no issues using graffiti in my own workflow.

I’m having the same issue, the first POST to /graphql is pending for quite some time, then fails. If I run the same query (query IntrospectionQuery…) via Postman, I get a proper response.

[neverfox]

I'd love to get this sorted since this is my first experience with considering graphQL for my next project (tired of REST endpoints proliferating like bunnies).

Make sure that MongoDB is running.

Not only is it running, but I'm looking at the pre-populated data in MongoHub, so I know that was successful.

[jbach]

I have tracked down the problem: It works if I don’t use bodyParser.json() in my express app. Seems to be a problem with graffiti / co-body / raw-body. Can anyone confirm?

[neverfox]

Since the example uses Koa, that might be the implicit default body parser there.

[tothandras]

Can you try the examples in the graffiti project? I can't introduce the errors you are facing with. 😕

[jbach]

@tothandras Regarding express, the problem arises if you add JSON body parsing as often suggested/needed by third party plugins. The workaround is to not use body-parser at root level or to exclude the /graphql endpoint via something like express-unless. Would it be viable to check if the body still needs to be parsed here?

[tothandras]

@jbach Would it be also viable to require body parsing by the plugin as other plugins do? :) Just drop it altogether and make it a requirement.

[jbach]

Probably. I checked up on co-body, it doesn’t seem to prevent double parsing like expressjs/body-parser does. I guess shifting that responsibility to the middleware would be my personal favorite.

[kaminskypavel]

+1 still having the same issue. any suggested work around?

[KATT]

+1

[tothandras]

Thanks for the report! I will fix this tomorrow.

@KATT @jbach @kaminskypavel @neverfox @dsifford
Can you try version 3.0.1 of graffiti? I've removed the body parsing from the middleware. The examples have also been updated in both repositories.

[kaminskypavel]

@tothandras , nope, unfortunately still getting Uncaught TypeError: Cannot read property 'getQueryType' of undefined .

also please update the readme to port 8081.

[jbach]

@tothandras, it does work for me. 👍
@kaminskypavel, are you sure you updated both graffiti and graffiti-mongoose?

[kaminskypavel]

I did a clean checkout and install, am I missing something?

[KATT]

Eureka! I was struggling as well and noticed I was using npm 2.14.7 and node 4.2.1.

Once I did a simple nvm use 5 it all kicked off for me. 🎉

[kaminskypavel]

what version of node was it?

[KATT]

$ node --version
v5.2.0
$ npm --version
3.3.12
