Cannot serve files (png)

'use strict';

const SetupEndpoint = require('./setup/setup.js');

module.exports = SetupEndpoint({
    name: 'attachment',
    urls: [{
                   params: '/{file}',
                   requests: [{
                       sendFile: true,
                       mimeType: 'application/pdf',
                       //response: '/attachments/1.png',

                       response: '/attachments/test.pdf'
                   }]
               }
               ]
});

I get the error message:

https://github.com/micromata/http-fake-backend/blob/master/server/api/fileTypes.js should work on your machine too.

It seems, that you are not using the latest version of the fake backend.

Can you check the version number in the package.json?
It should be > than 4. See releases.
