Error: Type Crb_ThemeOptions must define one or more fields.

Hi,

If I try to run GraphQL Code Generator, I get the following error: Type Crb_ThemeOptions must define one or more fields.

I think one possible solution would be:

Or do you've another idea?

Could you explain that solution? I don't understand how it fixes the issue 😕

Sorry, I guess, I wasn't clear enough. This error only occurs if I'm not making a theme_options container (Container::make('theme_options')). I think it's because the registerStaticObjectTypes function, as it now is, then registers an empty Crb_ThemeOptions object type.

To resolve that I took the register_graphql_object_type function (for Crb_ThemeOptions) and the register_graphql_field function (for crb_ThemeOptions) out of registerStaticObjectTypes, and stuck them into it's own registerStaticThemeOptionObjectTypes function. Then in the graphqlRegisterTypes function, I check if the current container is a theme_options container and only then (and the first time) I call the registerStaticThemeOptionObjectTypes to register the Crb_ThemeOptions type. Otherwise the (then empty) Crb_ThemeOptions type isn't registred. Which for me solves it.

Now I get it. I don't have the time to test it now, but I will accept it as you said you tested and it solved the issue for you.

Thank you for the contribution!

Thanks. I updated and tried it again. Now I can run GraphQL Code Generator without problems.
