Hello,

V4.24.3 custom API module ‘npm run develop’ fails with type error:

" TypeError: Error creating endpoint GET /single-types: Cannot create proxy with a non-object as target or handler ││ at getContentTypeProxy "

Module files:

// src/api/common/routes/single-types.ts
export default {
	routes: [
		{
			method: "GET",
			path: "/single-types",
			handler: "single-types.findSingleTypes",
			config: {
				policies: [],
				middlewares: [],
			},
		},
	],
};

// src/api/pages/controllers/single-types.ts
import { factories } from "@strapi/strapi";
import getSingleTypes from "../services/single-types";

export default factories.createCoreController(
	"api::pages.pages",
	({ strapi }) => ({
		async findSingleTypes(ctx) {
			try {
				const { slug } = ctx.query;
				const singleTypes = await getSingleTypes(strapi, slug);
				ctx.body = singleTypes;
			} catch (error) {
				ctx.throw(500, "Internal Server Error");
			}
		},
	}),
);

// src/api/pages/services/single-types.ts
import { Strapi } from "@strapi/strapi";
const getSingleTypes = async (strapi: Strapi, slug: string) => {
	try {
		const contentTypes = strapi.contentTypes;
		if (!contentTypes) {
			throw new Error("Content types are undefined.");
		}

		const singleTypes = Object.keys(contentTypes).filter(
			(key) => contentTypes[key]?.kind === "singleType",
		);
		const results: any[] = [];
		for (const type of singleTypes) {
			const entries = await strapi.entityService.findMany(
				`api::${type}.${type}`,
				{
					filters: { slug },
				},
			);

			if (entries) {
				const entriesArray = Array.isArray(entries)
					? entries
					: [entries];
				results.push(...entriesArray);
			}
		}
		return results;
	} catch (error) {
		console.error("Error fetching single type items:", error);
		throw error;
	}
};

export default getSingleTypes;

Thanks for taking a look!
