Usage in factories?

[evoactivity]

I have a factory like so

import Factory from '@ioc:Adonis/Lucid/Factory';
import ServiceProviderProfile from 'App/Models/ServiceProviderProfile';
import { ResponsiveAttachment } from '@ioc:Adonis/Addons/ResponsiveAttachment';
import { readFile } from 'node:fs/promises';
import { join } from 'node:path';

export default Factory.define(ServiceProviderProfile, async ({ faker }) => {

  const avatarImage = await ResponsiveAttachment.fromBuffer(
    await readFile(join(__dirname, '../../tests/resources/default-avatar.png'))
  );

  await avatarImage.setOptions({
    forceFormat: 'webp',
    keepOriginal: true,
    folder: 'avatars/service-provider',
    breakpoints: {
      xlarge: 1200,
      large: 800,
      medium: 300,
      small: 100
    }
  });
  await avatarImage.save();

  return {
    name: faker.name.findName(),
    avatar: avatarImage, // this ends up as null
    about: faker.random.words(100),
    specialties: faker.random.words(5).split(' ').join(', ')
  };
}).build();

The images are processed and saved to disk. avatarImage is the correct object before the return. Is there something else I need to do to make this work in a factory?
