Canvas Conversation Module Error

[Ray Yu]

Hi everyone,

 

I recently installed the open-source version of Canvas on one of the Ubuntu servers. Everything works fine except that I encountered two issues that I have absolutely no clues on how to fix:

 

1. I am not able to send messages to other users in the Conversation Module. I can send messages to myself. But when I try to send a message to other users registered in the same setup, I received the error message " "An unexpected error occurred, please try again". I have been searching the web and this forum but could not find anywhere that discusses this issue.

 

2. I cannot upload files by using the "Add Files" bottom but the drag and drop method works.

 

I really appreciate if somebody on this forum can provide me some suggestions on how to fix these issues.

 

Thanks a lot,

Ray

Hi Ray,

The Add Files one is an easy fix (if it is the regular problem) and has to do with file validation.

Go to your /app/controllers folder in your canvas install and edit the file 'files_controller.rb' e.g.:

sudo nano /var/canvas/app/controllers/files_controller.rb

Change line 44 to say (at the end):

skip_before_filter :verify_authenticity_token, :only => [:api_create,:create]

Cheers

Jude

Hi Jude,

 

I have tried your solution but it still did not work out. Instead, I got the HTTP ERROR (422).

 

Thanks,

Raymond

Make sure you're using an updated version of the Flash Player plugin. See this thread: https://groups.google.com/forum/#!topic/canvas-lms-users/BL5bV0F9TGw%5B1-25-false%5D

Are you getting it in all browsers? With updated flash?

I think since the drag upload (html) is working, this is likely to be a flash problem.

The second issue, as i guess, is because your web server or proxy server couldn't load the file upload flash player, you can try allow the swf extension.

Hi Ray, I have the same issue with the messaging module. There don't seem to be any related errors in the log files. Were you able to find a resolution to the get the messaging system working?

Thanks,

This is likely due to a MySQL regression. If you cherry-pick https://github.com/instructure/canvas-lms/commit/d67fe681022559f5ea417d12d80a21bd4d739841 on to the latest stable branch, it should work.
