When I try to preview a file I get the error: Unable to open 'Preview "filename.tex"': Cannot read property 'map' of undefined.

Windows 10 v.1.15.1

Are you using latexmk? If so, do you have Perl installed?

No I’m using pdflatex

Are you using latexmk? If so, do you have Perl installed? — You are receiving this because you authored the thread. Reply to this email directly, view it on GitHub, or mute the thread.

I have the same issue. OSX 10.12.6 . Latex preview 0.5.1, latex workshop 3.5.3. I haven't changed any of the default settings. The same issue happens if I switch "latex-preview.command" to latexmk (and I do have perl installed).

I realized that clicking the "view PDF file in new tab" does work (and updates properly on save), it's just the "Open Preview" button that gives the error.

I've got the same problem. Unable to open 'Preview "filename.tex"': Cannot read property 'map' of undefined. Using the default settings, with perl, Tex Live, Latex Workshop installed. Win10.

Same problem on Mac OS 10.13.1.

same problem macos 10.13.2, visual studio code, latex workshop and latex preview

Same problems on macos 10.13.2

Same problem on mac os 10.12.6

Windows 10, Pearl, TeX Live and LaTeX workshop installed - Same Problem. Also the "View LaTeX PDF File in new tab" Does not work for me. Apart from the "Cannot read property 'map' of undefined" error when clicking "Open Preview"

Edit: The same happens for both on Void Linux with TeX Live.

Same problem on mac os 10.11.6

Any update?

Unfortunately I'm unable to replicate this issue. If someone has a basic example project they can zip up and attach to the issue it would be appreciated.

Or if someone can run the extension under the vscode extension debugger and capture a stack trace that would be even better. All you need to do is clone the extension repository, open the folder in vscode and run the project using F5.

@ajshort I just tried running it using the extension debugger, but it returns another error (in German):

BUT somehow it works when using it while I have the folder opened when I try to open the preview.
Since I don't know anything about VS code - I actually just looked for a Hi-DPI alternative to running gummi inside WSL using an X-server 😅 - I don't know how to provide more information on this topic, sorry 😕 (This is on Windows, obviously)

can confirm @C1710 , this issue only appears when you open the file directly, it wont once you open the folder (File -> Open Folder), select the tex file - everything works. if you open the file directly without the folder it will throw the mentioned error

Can confirmed @eisenwinter at vscode 1.21.0, using open folder and the issue didn't come up again.

@eisenwinter , you're right. Opening the complete folder instead of just the .tex file solved the problem. I guess that's because it uses others files that are created with the .tex file.

ERROR: command 'vscode.previewHtml' not found.

Now, vscode.previewHtml has been removed? You also can see https://github.com/Microsoft/vscode-cosmosdb/issues/1070 .

More to the point vscode.previewHtml was replaced by the webview api: https://github.com/Microsoft/vscode/issues/62630. All the sudden, latex preview has stopped working because I think it finally disappeared in the current update to vscode?
