Enhance javascript_nodejs/15.handling-attachments sample for use file types different than images

[lord-maestro-encora]

attachmentsBot.js file works with image file samples.
however when I tried changing to pdf or xlsx files the output says RestError: Unknown attachment type
this is the attachment sent:

{
  name: 'MLBOOK.pdf',
  contentType: 'application/pdf',
  contentUrl: 'https://ai.stanford.edu/~nilsson/MLBOOK.pdf'
}

Error returned

[onTurnError] unhandled error: RestError: Unknown attachment type

It would be very helpful to offer file outputs different than image files. Also if another sample offers options to show how to handle pdf or other document files would be very appreciated.

@lord-maestro-encora - Thank you for your patience.

Can you tell me which version of the SDK you used when you tested this?
Does the problem persist using the most recent version?
Lastly, which client are you using to communicate with your bot (WebChat, Slack, etc.)?

hi @stevkan Thank you so much for your answer
The issue persists.
It was using Microsoft Teams
Can you show me how to obtain SDK version you've requested? Is it a node.js package?

[stevkan]

@lord-maestro-encora - The version will be listed within the package.json file located in your project's root folder. It will, for example, look something like "botbuilder": "^4.22.2".

Thank you @stevkan
"botbuilder": "^4.20.0"
