Digging into this error message led me to this WP Graphql discussion: wp-graphql/wp-graphql#373. Which was formalized into https://docs.wpgraphql.com/guides/authentication-and-authorization/. Very helpful!

The relevant part of the docs:

A public, non-authenticated request would return a null value for the field and would return an error message in the GraphQL response. However, it wouldn’t block the execution of the entire GraphQL request, just that field. So, if the request had a mix of publicly allowed fields and private fields, GraphQL would still execute the public data.

Which leads to my questions:

• Why are the allSettings.generalSettingsEmail and generalSettings.email actually necessary for the build process?
• If part of a larger query, shouldn't this query actually be succeeding and just leaving those fields blank?

@jasonbahl -- could you provide more guidance on how to actually use the wp-graphql plugin with the authentication plugins you mention in the documentation?

Workaround:

    {
      resolve: `gatsby-source-wordpress-experimental`,
      options: {
         AllSettings: {
           excludeFieldNames: ['generalSettingsEmail'],
         },
         GeneralSettings: {
           excludeFieldNames: ['email'],
         },
       },
    },

To bypass the auth-only fields.
