Observed behavior

• SVG is successfully downloaded (yes, actual download works)
• An error message is shown (see below) and Mattermost has to be restarted

Log Output

Additional Information

• Tested on the web interface (current Firefox) and the issue does not show up there.
• Downloading a different file type (JSON) works, no issues.
• Downloading an image (PNG) works as well. But here the UX is different, as I first have to click on the image to show it and, when it's shown, I can click the download button shown at the top-right.

My Desktop Mattermost crash too when I try to download a png or jpeg file but the error is different, I don't know if this is related to the same issue.

I'm on Manjaro with kernel 6.10

The same error appears when downloading *.dwg file.

s.nativeImage.createThumbnailFromPath is not a function, app crashes.

@bjoernmartin I can't reproduce your specific issue, is it consistently reproducing for you everytime? I might need to add a crash check here.

The other issue people are commenting about in this ticket is this one: #3129, which is a separate issue.

[bjoernmartin]

@devinbinnie yes, happens for SVGs every time.

I just created a new private channel, uploaded another SVG and tried to download it. Same error.

I then downloaded an SVG from the internet, just in case it is something we do with SVGs internally. I chose https://www.svgrepo.com/svg/499714/rocket. No change, still getting the error message on download.

[devinbinnie]

Thanks @bjoernmartin. I still can't reproduce it, so I'm wondering a couple things:

• Are you in a managed environment? (ie. is there a group policy configured on you system)
• Is the file being saved to a network drive? I'm wondering if it's having issues grabbing thumbnails from there.

[bjoernmartin]

* Are you in a managed environment? (ie. is there a group policy configured on you system)

Nope. I installed the computer myself and my company does not even support managing Windows machines :)

* Is the file being saved to a network drive? I'm wondering if it's having issues grabbing thumbnails from there.

Nope. The installation is local and not tampered with in any way. It runs on a Bitlocker-encrypted system, but I cannot imagine this being an issue here.

[bjoernmartin]

@zwolinski you mentioned getting "the same" error. This refers to the original one from me?

 Failed to get thumbnail from local thumbnail cache reference

Or the additional one mentioned by @dragonis41 ?

s.nativeImage.createThumbnailFromPath is not a function

Just trying to figure out if I'm the only one with "my" error.

@Annavar-satish that is a different issue and got solved via #3129, as stated by @devinbinnie before. That fix is not released yet though (we are still at 5.9.0, 5.9.1 and 5.10.0 should contain the fix).

[licaon-kter]

So Linux crashes because of #3129 and now Windows crashes because of this one. 😞

I looked at an image and then wanted to download it. The download was effective, but the error still occurred. Tested several times. Fedora Linux

#3188 is very similar in behavior, but on a different platform. I do believe they are related.

[goutnet]

After more analysis, it seems we have the same issue on Linux. I close #3188 since it would be a duplicate of this issue, with the same message.

As mentioned above #3188 could also be another instance of #3129, I'll wait for the 5.9.1 to confirm

[devinbinnie]

#3129 is fixed on v5.10.0-rc.2 if anyone wants to try that.
It might also fix the issue in the screenshot above.
