Hi…
i have this in config/myFunctions/utils.js

module.exports = {
  CheckImages(files) {
    var claves = Object.keys(files);
    const validTypes = ["image/jpeg", "image/jpg", "image/bmp", "image/png"]

    for (let i = 0; i < claves.length; i++) {
      const clave = claves[i];
      const valor = files[clave];
      if (!validTypes.includes(valor.type)) {
        return false;
      }
    }
    return true;
  },
}

and in the endpoint

const { CheckImages } = require("../../../../config/myFunctions/utils");
const files = ctx.request.files;
    if (files) {
      if (!CheckImages(files))
        return ctx.badRequest('Formato de imagen no válido');
    }
