Describe the bug

Hi, I'm trying to create a custom policy for an API. I edited the core router file for an API named class (which is a collection type created by the Content Type Builder) with the code below. However, when I try to run Strapi again, I get the following error: Error: Error creating endpoint GET /classes: Policy not found.

I attempted to create the policy for the API using the npm strapi generate command and in the router I replaced the function with the policy name, but the same issue persists. The only difference is that the policy name appears in the error message.

Thanks

Steps to reproduce the behavior

Add policy into API core router

Expected behavior

Working policy

Code snippets

'use strict';

/**
 * class router
 */
const { createCoreRouter } = require('@strapi/strapi').factories;

module.exports = createCoreRouter('api::class.class', {
    prefix: '',
    only: ['find', 'findOne'],
    except: [],
    config: {
        find: {
            auth: false,
            policies: [
                (policyContext, config, { strapi }) => {
                    console.log("Policy test")
                }
            ],
            middlewares: [],
        },
        findOne: {},
        create: {},
        update: {},
        delete: {},
    },
});
