Attachment's DownloadURL is missing when attaching cloud files

[mutt0-ds]

Versions

• botbuilder@4.22.2
• node v18.19.0
• Microsoft Edge | 127.0.2651.86
• Windows 10 Pro 22H2

Describe the bug

TurnContext.activity.attachments doesn't show the files attached using "Attach Cloud Files". It only works with "Upload from this device"

To Reproduce

Steps to reproduce the behavior:

1. Run the EchoBot demo
2. Click on '+' -> Attach File -> Attach Cloud Files
3. Log context.activity.attachments

   private test(context: TurnContext): Message {
       const { attachments } = context.activity;
       console.log('attachments', attachments);

   

Expected behavior

To see the downloadUrl in context.activity.attachments just like it happens when uploading the file from the device

@mutt0-ds - Thank you for your patience. Are you still having an issue with this?

Unfortunately, I have been unable to repro the issue. Every attachment I have sent using 'Attach cloud files' shows the file details in the activity.attachments property array. For example:

attachments: [
    {
      contentType: 'application/vnd.microsoft.teams.file.download.info',
      content: [Object],
      contentUrl: 'https://XXXXXXXXXXX/personal/XXXXXXXXXXX/Documents/DahliaList.xlsx',
      name: 'DahliaList.xlsx'
    },
    {
      contentType: 'text/html',
      content: '<p>Sending a file</p>'
    }
  ]

Can you try capturing the attachment in the activity handler's "on message" handler and see if the result is the same?

[mutt0-ds]

Thank you for the assistance! I have used the handler as the following

import { TeamsActivityHandler, TeamsInfo, TurnContext } from 'botbuilder';

export class TeamsBot extends TeamsActivityHandler {
    constructor() {
        super();
        this.onMessage(async (context: TurnContext, next: () => Promise<void>) => {
            console.log(`Received message: ${context.activity.text}`);

            const attachments = context.activity.attachments;
            if (attachments) {
                for (const attachment of attachments) {
                    console.log(`Received attachment: ${JSON.stringify(attachment)}`);
                }
            }
            const response = `Received message: ${context.activity.text}`;
            await context.sendActivity(response);
            await next();
        });

And the issue persists.

Do I need to change something in my code?

@mutt0-ds - I'll test your code tomorrow and let you know what I find. In the meantime, can you tell me the size of the file you are trying to send?

[mutt0-ds]

Much appreciated! In the example, the .png is 80kb and the .pdf is 1MB, I also tried with other files of various sizes during my tests.

@mutt0-ds - I tested your code and it is working without issue for me.

It's possible this is an issue related to your tenant and/or OneDrive. The notes listed in this portion of the Teams docs regarding storage may point to a cause. Namely,

If you don't have SharePoint Online enabled in your tenant, Microsoft Teams users can't always share files in teams. Users in private chat also can't share files because OneDrive for Business (which is tied to the SharePoint license) is required for that functionality.

and

all compliance rules configured at the tenant level are followed.

I don't know that any of the above is the cause. Only that any of it could be. I would expect an error or warning to appear or the option to send be disabled vs. the attachment just being ignored, but I don't know what the expected functionality should be.

Regardless, at the moment, this is looking less like a BotFramework issue and more like a configuration issue. But let me know what you discover.

I would also recommend posting this issue on Microsoft's Q&A docs forum, tagged with microsoft-teams, and see what response you get. If you do so, include details such as it's not reproducible and your code worked fine when tested.

Will do! Thank you so much for your help! I will keep you posted

This needs to be reopened when attaching files that are shared to you so not in your personal it doesn't appear as anything but can be sent.
