Gatbsy source strapi locale 'all' for singleTypes

[NevenaKirova]

i changed the controller configuration in strapi using this function :
module.exports = ({ strapi }) => ({
async find(ctx) {
if (ctx.query.locale === 'all') {
const localesArray = await strapi.plugins.i18n.services.locales.find()
const locales = localesArray.map(locale => locale.code);

  let data = [];

  for (let locale of locales) {
    ctx.query.locale = locale;
    const response = await super.find(ctx);
    if (response) data.push(response.data);
  };

  const meta = {};
  return { data, meta };
}

return await super.find(ctx);

}
});

so i can get all the locales. It is kind of working but only for two pages. For the rest of the pages it either returns only the default locale or i can no longer see it in the Graphql schema. The problem with the data missing from graphql happens when i add

pluginOptions: {
	i18n: {
		locale: 'all',
	},
},

to the singleType configuration, which is needed, so i can get all locales.

{
        singularName: 'privacy-policy',
          queryParams: {
	          populate: '*',
          },
          pluginOptions: {
	          i18n: {
		          locale: 'all',
	          },
          },
 },
 {
        singularName: 'about',
        queryParams: {
	        populate: '*',
        },
        pluginOptions: {
	        i18n: {
		        locale: 'all',
	        },
        },
 },					
{
        singularName: 'landing-page',
        queryParams: {
	        populate: {
		        background_image: {
			        populate: '*',
			        locale: 'all',
		        },
		        partners_logos: {
			        populate: '*',
			        locale: 'all',
		        },
		        integrations_logos: {
			        populate: '*',
			        locale: 'all',
		        },
		        benefits: {
			        populate: '*',
			        locale: 'all',
		        },
		        services: {
			        populate: '*',
			        locale: 'all',
		        },
		        news_details: {
			        populate: '*',
			        locale: 'all',
		        },
		        testimonials: {
			        populate: '*',
			        locale: 'all',
		        },
	        },
	        pluginOptions: {
		        i18n: {
			        locale: 'all',
		        },
	        },
        },

Those are three examples for one that is working, one that is only returning the default locale and, one that is not appearing in graphql after this configuration (landing-page)
