QUESTION

Meaning of "Expected undefined to be a GraphQL type"?

Asked 2020-Dec-06 at 18:03

I am setting up my first GraphQL endpoint with graphql and graphql-express. My MongoDB schema has two types: User and Card, where a User can have many Cards. I set up the root types and resolvers with no issues. I can query and mutate users and cards in the database.

My problem comes when I try to nest cards in users, and I get Error: Expected undefined to be a GraphQL type. The error only appears when I set UserType.fields.cards.type to be an instance of graphql.GraphQLList, yet I had an identical field value in QueryType.js, and that works fine.

Looking at other questions on Stack Overflow, it appears that my problem could be a cyclical reference between my User and Card types, but I am struggling to find any problems in my code. Is there something I'm missing here?

The full stack trace is:

ANSWER

Answered 2020-Dec-06 at 18:03

In UserType.js, I destructured the output of require('./CardType') which resulted in CardType being undefined. GraphQLList expected an instance of GraphQLObjectType but instead received undefined, hence the error.

Deploy Express server and test GraphQL API via CircleCI

Asked 2019-Jul-24 at 14:46

I wish to test that my Express server launches properly and that my endpoint retrieves the correct information. I wish to do this in CI so that I can monitor when my application is no longer working, if I make any changes in the future.

It's a very simple application, my server looks like this:

npm start & won't wait for server to start, are you sure your server is listening on the port by the time your test makes a request? I.e. do you have 'Server running on port: 1337' in your console on CI? If not then try running sleep 3 before starting tests

Resolvers let you define functions that will get executed only when a field is requested.

So we can define function on the Book type for author and on Author type for books, lets assume that author field contains author id and books contains array of book ids

GET query missing: Implementing GraphQL Using Apollo On an Express Server

Asked 2019-Jan-19 at 13:02

I'm following the tutorial here: Implementing GraphQL Using Apollo On an Express Server and I'm getting the error GET query missing in the browser at http://localhost:7700/graphql.

First I typed all the code myself. When I encountered the error, I downloaded the code from GitHub: kimobrian/GraphQL-Express: An Express Server implemented using GraphQL to eliminate the possibility that I had made a mistake. However, I'm still getting the same error.

I presume it is better to provide the link to the repo rather than paste the code here because I'm using the same code from the repo. Also, I am not sure which file might contain the problem.

Both the API and the package name itself have changed since that tutorial was written (the package is now apollo-server-express). You no longer need to import cors or body-parser. The simplest way to get started is to actually just use apollo-server:

I stripped down your example and added a minimal version of what you need to get it up and running.

Basically what you're missing is the part where babel actually goes and transpiles your code. I don't know if webstorm does that for you, I'm using VS code.

get Index from an Array using Express + GraphQL

Asked 2019-Jan-03 at 13:59

I am just getting my hands dirty with GraphQL using Express. I am following the Academind YouTube Series for GraphQL-Express-Node-React. I have just setup a basic GraphQL Schema where I have hardcoded Array of Strings which is returned. I want to create a Query which gives me the index of the element from this hardcoded array using GraphQL (graphiql)

ANSWER

Answered 2019-Jan-03 at 13:59

This error is not specific to GraphQL.

Array.findIndex expects a function to be passed in as its first parameter. The function is called for each element in the array until the function returns a truthy value, at which point it returns the index of that element. The value of args.eventName is not a function (it's a String) so you end up with that error.

Either pass it a function, like:
