Pagination not working for "api/upload/files" endpoint

Hi guys,

I’m facing the same issue and needed to use pagination[page]&pagination[pageSize].
Here is how I could make it work. The important part is using findPage() instead of findMany().
Hopefully this helps someone.
BTW, I found a related issue for listing users. It would be great to have those plugins following the same standard.

# extensions/upload/strapi-server.js

const { sanitize, validate } = require('@strapi/utils');
const FILE_MODEL_UID = "plugin::upload.file";

const sanitizeOutput = async (data, ctx) => {
  const schema = strapi.getModel(FILE_MODEL_UID);
  const { auth } = ctx.state;

  return sanitize.contentAPI.output(data, schema, { auth });
};

const validateQuery = async (data, ctx) => {
  const schema = strapi.getModel(FILE_MODEL_UID);
  const { auth } = ctx.state;

  return validate.contentAPI.query(data, schema, { auth });
};

const sanitizeQuery = async (data, ctx) => {
  const schema = strapi.getModel(FILE_MODEL_UID);
  const { auth } = ctx.state;

  return sanitize.contentAPI.query(data, schema, { auth });
};

module.exports = (plugin) => {
  plugin.controllers["content-api"].find = async (ctx) => {
    ctx.query = {...ctx.query, ...ctx.query?.pagination}

    await validateQuery(ctx.query, ctx);
    const sanitizedQuery = await sanitizeQuery(ctx.query, ctx);
    const data = await strapi.plugin("upload").services.upload.findPage(sanitizedQuery);
    const {results, pagination} = await sanitizeOutput(data, ctx);
    
    ctx.body = {
        data: results,
        meta: {
            pagination: pagination,
        },
    };
  }

  return plugin;
};
