cannot fetch empty fields

[deebov]

Hi there

Gatsby fails to build the project if I try to fetch an empty field from Strapi. e.g. I have the Post content type in Strapi but it does not contain any post. So, when I try to fetch allStrapiPost it throws an error during the build process.

The error message:

P.s. I would really appreciate if someone could help solving this issue 🙏

Error suggests that you're querying allStrapiPosition, I'm confused. Also did you change public user permision so it can actually be read?

I'm facing same issue. Currently I have to create dummy-content just to make sure that every GraphQL type is created properly, just to bypass this problem.

I've seen an API for quering content types in Strapi (it was /content-manager/content-types and /content-manager/groups), it may solve this problem, because we would be able to query correct types, but with no results. But a PR for this would be required, since it changes how gatsby-source-strapi works now.

EDIT:

Hardcore workaround is to create type for content type, that might be unavailable. So for example, having an Article type with:

• content - rich text
• title - string

a type for Gatsby/GraphQL would look like this:

module.exports.createSchemaCustomization = ({ actions }) => {
    const { createTypes } = actions;

    const typeDefs = `
        type StrapiArticle implements Node @infer {
            title: String
            content: String
            created_at: Date @dateformat
            updated_at: Date @dateformat
            strapiId: Int
        }
    `;

    createTypes(typeDefs);
};

@rozpuszczalny Thank you for this, what did you use for image/file types? Especially, that I'm using fluid images in Gatsby, thank you.

@waynehaffenden I haven't used gatsby with images. However, you can go to /__graphql playground, click in the upper right corner on "Docs >", and then type in a name of the type. See attached screenshot:

@rozpuszczalny Thank you

To prevent errors dealing with content-types without existing records, just use the gatsby-plugin-schema-snapshot plugin. Set the "update" option to "true" and build your app with all content-types having at least one record (e.g. a dummy record). That creates a schema.gql file in the root of your app folder. Afterwards, set the plugin's "update" option to "false" and remove your dummy record. No complaints anymore while gatsby builds :)

@kjoscha Thank you! You saved me. ♥️
