SlackBridge - Slack -> RC File Attachments not working

[mrplow]

Description:

Uploading a file from a synced private channel in slack isn't working. Messages sync 2-way fine

Server Setup Information:

• Version of Rocket.Chat Server: 0.62.1
• Operating System: Debian 8.10 64bit
• Deployment Method(snap/docker/tar/etc): docker-compose
• Number of Running Instances: 1
• DB Replicaset Oplog: Enabled
• Node Version: 8.9.3
• mongoDB Version: 3.4.13

Steps to Reproduce:

1. Setup RC to sync with Slack by putting in your slack bot token
2. Test by adding your bot to a channel in slack and send a message
3. Upload a file in slack, nothing comes across in RC

Expected behavior:

The same file to show in RC

Actual behavior:

Nothing

Relevant logs:

Exception in callback of async function: Error: Meteor.userId can only be invoked in method calls or publications. at AccountsServer.userId (/app/bundle/programs/server/packages/accounts-base.js:516:35) at AccountsServer.user (/app/bundle/programs/server/packages/accounts-base.js:125:23) at Object.Meteor.user (/app/bundle/programs/server/packages/accounts-base.js:340:19) at Filter.validateFileUpload [as onCheck] (/app/bundle/programs/server/packages/rocketchat_file-upload.js:95:25) at Filter.check (/app/bundle/programs/server/packages/jalik_ufs.js:595:53) at FileUploadClass.insert (/app/bundle/programs/server/packages/rocketchat_file-upload.js:590:14) at requestModule.get.Meteor.bindEnvironment.stream (/app/bundle/programs/server/packages/rocketchat_slackbridge.js:857:17) at runWithEnvironment (packages/meteor.js:1240:24)

I checked my bot's setting and it seems correct. I switched from external to internal hubot. I installed a fresh RC to check my Permissions settings (what a pain since the users aren't showing in the same order since anonymous and leader are newer) (also checking a permissions box by accident is very easy and not obvious if using a touch screen).
Anyways nothing helped and I always receive the same error.

PR #10269 changed the application to send a message with a link to the attached files.

I noticed that when I use /slackbridge-import it did import the pictures from slack to rocketchat. First I noticed that the Maximum File Upload Size (in bytes) at the File Upload settings section, was to small for certain pictures/files. I increased it and ran /slackbridge-import again and more pictures imported

The problem is the same on the other side, meaning that if a file is uploaded on the Slack channel, it is not visible on the Rocket.Chat side. I suppose this bug was only making reference to file upload in Rocket.Chat not visible in Slack channel or was it both way ? Is it planned to fix those bugs because this is pretty annoying, we can't use Slack integration in this case, because file upload in channels is pretty common, still not working with 0.71.1. Any plan to fix this soon ?

When a file is uploaded on slack, you should be getting a link to download it on Rocket.Chat. Do you get any kind of error message on the logs?

just did a test on a slack channel, I get the following info below in /var/log/syslog
I receive the description text on the Rocket.Chat side, but no link to anything....
I see the "Not Running" is there some other specific service ?

No, that is unrelated. I'll run some tests here to see if I can find anything wrong.

[1000ouz]

Did it run well with your tests ? Is there some more specific logs I can check except /var/log/syslog ?

[Hudell]

I've confirmed the bug: it only happens with newer data. A few months ago slack change the structure in which they store their files, that is probably what is causing this issue.

any update on this? what part of the code can we look in to help?

[L3nny5]

Any idea when this will be fixed? It would really help us to migrate from Slack to Rocket.Chat.

Closed via #14273

For me it does not seem to be fixed. Now I get a Link displayed in the channel, which is better. However it is not displaying it. Why can't Rocket.Chat import the file which is displayed in Slack?
