I’m using Strapi v4 as my backend and I want to send an email using Nodemailer in the beforeCreate or afterCreate lifecycle hook of a content type. I need to access a file uploaded during the creation of the content and attach it to the email. Here’s an example of my code:


beforeCreate: async (event) => {
  const ctx = strapi.requestContext.get();
  const { full_name, email } = JSON.parse(ctx.request.body.data);
  const file = ctx.request.files;
  const trackingCode = await strapi.config.helperFunction.generateRandomItn(event);
  
  try {
    const emailOptions = {
      to: email,
      subject: subject,
      html: content,
      attachments: [
        {
          filename: file.name,
          path: file.path,
        },
      ],
    };
    
    await strapi.plugins['email'].services.email.send(emailOptions);
    strapi.log.debug(`Email sent`);
  } catch (err) {
    strapi.log.error(`Error sending email`, err);
    throw new ApplicationError(`Error sending email: ${err}`);
  }
},

However, I’m unsure how to properly access the file within the lifecycle hook and attach it to the email. I would appreciate any guidance or code examples on how to achieve this.

Thank you!
