Hi Tobi.

Thanks for using the plugin.

These error markers are intended and valid behavior since the plugin only ships with the standard directives that are part of the GraphQL spec.

For frameworks such as Apollo, or any other, it's up to the developer to declare them. There's an example with @client at https://github.com/jimkyndemeyer/graphql-config-examples/tree/master/extend-client-fields-and-directives you can look at.

Once you've declared the directives you also get completion etc.

Best regards,
Jim

Fantastic, thanks for getting back to me @jimkyndemeyer! Declaring the directive myself worked 👍
