"Open in Kami" not working consistently on Chromebook

We are experiencing some issues when students right click on pdf’s in Canvas (our LMS) and select “Open with Kami” - most do, some do not. The ones that don’t, downloads the file.
We have ensured that every student has installed Kami to their google drive and have selected the “open all files with Kami” preference. The students, chromebooks and accounts are set up identically, but perform differently.
We would prefer to have documents open in Kami consistently to avoid student confusion on WHERE their documents are.
Any ideas what we might be doing wrong? Or settings or instructions we have missed?


When Kami is loading a file from a web link in that way we do some checks to make sure it looks like a file we will be able to open - I think what is happening here is that those checks are not passing sometimes. I’m not sure why it would be only some of the time, is there any pattern to which files work and which ones don’t?

One thing I have noticed is that in the case where the user explicitly chose to open with Kami using the right-click-> Open method (rather than just clicking on a link to a file), we should probably bypass those checks and always attempt to open the file with Kami. I’m going to make that change and get back to you.


We have seen where students on the same model chromebook, same version of chrome, in same course, with the same assignment (linked pdf) using the right click >open method and have different results. I appreciate your response and would like to know if and when you make that change where those “checks” may bypass when students choose to open with Kami. Thank you.

We’re testing the changes now, it should be in a 2-4 days.

Thank you for the update!

I’ve just released the update with these changes, it’s version 2.0.10166. You should get the extension update over the next few days.

I’m not completely sure if what I changed here is the cause of what you are seeing or not, so will be keen to hear if you see it working consistently once they have the update or not.
