Sketchtool Bus Error

Share an issue
1

Hi there, when attempting to run sketchtool on the command line I’m getting a bus error. It seems to occur solely when opening files.

This is the command and output:

/Applications/Sketch.app/Contents/MacOS % ./sketchtool list pages /Users/ryanconnolly/Downloads/sketchfile.sketch
objc[26582]: Class MSAssetCollection is implemented in both /System/Library/PrivateFrameworks/CoreMediaStream.framework/Versions/A/CoreMediaStream (0x1e72df3d0) and /Applications/Sketch.app/Contents/Frameworks/SketchModel.framework/Versions/A/SketchModel (0x104675fa0). One of the two will be used. Which one is undefined.
zsh: bus error  ./sketchtool list pages /Users/ryanconnolly/Downloads/sketchfile.sketch

I ran the command in LLDB and recieved a pretty lengthy backtrace. Here are the first few frames:

I’m not sure if the above MSAssetCollection warning is related, but have included it anyway.
I’m using the trial version, not sure if that makes a difference.

Operating system: Sonoma 14.1.2

Any help is appreciated.

Thanks

Hello @ryaan! :wave:

Thanks a lot for gathering this information for us! I’ve already passed this on internally, but I would like to verify something.

We’ve been recently working on this MSAssetCollection error, and I’m happy to say that we’ve found where the issue was and added a fix in the beta version. It will be integrated into the next release, but if you wish to, you can test it right now by downloading the beta version here).

Note: Please carefully read the disclaimer on the beta page before proceeding. As always, we recommend using these builds with copies of your Documents, just in case.

That would help us to confirm if this solves the issue you are currently experiencing.

Thanks for the reply. I tried the Beta version and the MSAssetCollection warning is gone, but the bus error remains.

Interesting… Then this is a new issue on its own.

I will open an investigation to analyze this issue, but we would need a little bit more context on the situation. Could you send us the document you are reproducing this with?

(If you can’t share it publicly here, let me know, and you can send it to me via the productsupport@sketch.com email).

Cheers! :pray:

Attached is a simple document I created that replicates the issues.

This is the command and output.

(base) ?138 ~/Downloads/Sketch Beta.app/Contents/MacOS % ./sketchtool export preview /Users/ryanconnolly/Documents/test3.sketch
zsh: bus error ./sketchtool export preview /Users/ryanconnolly/Documents/test3.sketch

Thanks for the feedback, @ryaan

Let us investigate a little bit, and I’ll get back to you with any new information! :smile:

Interesting… I’ve tried to reproduce the issue on my system, but I don’t receive any error like that :thinking:

Not with the “list pages” or “export preview” commands:

CleanShot 2023-12-07 at 10.21.12
CleanShot 2023-12-07 at 10.21.121265×173 50.5 KB

I can see that you are using this path:

~/Downloads/Sketch Beta.app/Contents/MacOS % ./sketchtool export preview

And I’m using this one:

/Applications/Sketch Beta.app/Contents/Resources/sketchtool/bin/sketchtool export preview

Could you try it out and see if the outcome is different?

Cheers! :pray:

I found this while Googling part of my stack trace, it seems to be a known problem, narrowed down to having libpng installed to /opt/homebrew/lib and having /opt/homebrew/lib in env var DYLD_LIBRARY_PATH. libpng causes GUI apps to crash with EXC_BAD_ACCESS · Homebrew · Discussion #5420 · GitHub

Is there any particular reason to have /opt/homebrew/lib in your (global?) DYLD_LIBRARY_PATH?
