Bug report

Required System information

• Node.js version: v20
• Yarn version: v1
• Strapi version: 5.0.0-beta.5
• Database: SQLite
• Operating system: Linux Mint 21.3
• Is your project Javascript or Typescript: Javascript

Describe the bug

Attempting to play around with custom controllers in Strapi 5 I was attempting to set a custom ctx.query and noticed that type errors are being thrown around the structure of ctx.query

Steps to reproduce the behavior

1. Create a custom route
2. Create a custom controller
3. Attempt to manually set the value of ctx.query
4. Request the custom controller
5. See error

Expected behavior

No breaking changes were recorded for the object based populate syntax thus this was valid in Strapi 4 and should also be valid in Strapi 5

Screenshots

Code snippets

Route:

module.exports = {
  routes: [
    {
      method: "GET",
      path: "/tests/custom/example",
      handler: "api::test.test.exampleAction",
    },
  ],
};

Controller:

"use strict";

/**
 * test controller
 */

const { createCoreController } = require("@strapi/strapi").factories;

module.exports = createCoreController("api::test.test", ({ strapi }) => ({
  async exampleAction(ctx) {
    await this.validateQuery(ctx);
    const defaultQuery = {
      populate: {
        createdBy: {
          fields: ["id", "username"],
        },
        updatedBy: {
          fields: ["id", "username"],
        },
      },
    };

    if (!ctx.query) {
      ctx.query = defaultQuery;
    }

    const sanitizedQuery = await this.sanitizeQuery(ctx);
    const entities = await strapi
      .documents("api::test.test")
      .findMany(sanitizedQuery);

    const sanitizedData = await this.sanitizeOutput(entities, ctx);

    try {
      return this.transformResponse(sanitizedData);
    } catch (err) {
      return err;
    }
  },
}));

Schema:

{
  "kind": "collectionType",
  "collectionName": "tests",
  "info": {
    "singularName": "test",
    "pluralName": "tests",
    "displayName": "test"
  },
  "options": {
    "comment": "",
    "populateCreatorFields": true
  },
  "attributes": {
    "test": {
      "type": "string"
    }
  }
}
