Problem building against WPGrapQL

[richardaubin]

Describe the bug

This appears to be an issue similar or the same I had with StrawberryShake against the same schema source.

How to Reproduce
Create a Wordpress website: download free app https://localwp.com/ to create a local wordpress installation.

Install the WPGraphQL plugin: https://wordpress.org/plugins/wp-graphql

Go through zeroql setup steps, and when reaching the build step, build fails with 14 errors:

I believe this might be an issue with enums. The schema contains enums that begin with _ which are the 14 errors in the generated source code.

enum MediaItemSizeEnum {
LARGE
MEDIUM
MEDIUM_LARGE
THUMBNAIL
WOOCOMMERCE_GALLERY_THUMBNAIL
WOOCOMMERCE_SINGLE
WOOCOMMERCE_THUMBNAIL
_1536X1536
_2048X2048
}

After going and manually fixing the enum errors to include the _ in the generated source, a whole bunch of other errors sprang up:

This is sdl version of the schema.

I have fixed the issue with the enums(6.2.0-preview.3), but as you showed, it now fails with interfaces. Some fields in the schema have additional arguments compared to those defined in interfaces. I will have a look later today.

[richardaubin]

I appreciate that.

[richardaubin]

Hello, are you making progress?

I fixed the situation that was responsible for the first two issues. However, there is another issue. The schema contains the interfaces Node and Product. Then the Product is assigned to Node property. In GraphQL, it works. In C# is doesn't because the Product has to implement Node. I am thinking about how to fix it.

How do you get this schema? Looks like it is broken. There are interfaces that are not explicitly "implemented". For example, PageEditorBlock and EditorBlock. They are identical and have zero relations between each other on the schema level, but properties use them as if they are identical.

The same issue was with Node in lots of places. I decided to force the generation to "believe" that it is okay because it is a part of the GraphQL Relay. However, with the EditorBlock, it is not so straightforward.

How do you get this schema?

Nevermind. You already mentioned it in the initial description.

Thanks for staying on this.

Wordpress has various 'post' types, including 'post' and 'pages' by default.

The EditorBlock interface is provided by a 3rd party plugin which adds graphql functionality for one of the core features of wordpress, the Gutenberg Block editor, which allows users to assemble their content using modules/bocks r: https://github.com/wpengine/wp-graphql-content-blocks/tree/main

This explains why the different interfaces.... They are used to determine under which contexts (post, page, etc..) they can be used. Probably to not allow them to appear on post types not supported by the Gutenberg editor and related enabled post types in the main graphql plugin.

[richardaubin]

So though they each have the same properties, the interfaces are only being used as markers.
