View() on lists shows blank pane — jquery.json-viewer.css path mismatch in 2.8.7 #1687
Description
Environment
VSCode R Extension version: 2.8.7
OS: Fedora 43
R version: 4.5.3
Describe the bug
Calling View() on an R list opens the viewer pane but renders nothing.
The webview logs the following error:
ERR Webview.loadLocalResource - Error using fileReader. requestUri: file:///home/.../.vscode/extensions/reditorsupport.r-2.8.7/dist/resources/jquery.json-viewer.css resourceToLoad: file:///home/.../.vscode/extensions/reditorsupport.r-2.8.7/dist/resources/jquery.json-viewer.css
Root cause
The extension references dist/resources/jquery.json-viewer.css but the file is actually located at dist/resources/json-viewer/jquery.json-viewer.css. The resource moved into a subdirectory but the path reference was not updated.
Workaround
Copying jquery.json-viewer.css from dist/resources/json-viewer/ up to dist/resources/ restores functionality.
Expected behavior
View() on a list should display the tree viewer without manual file manipulation.

Is there any discernible impact from the missing jquery.json-viewer.js? I'm getting that same errors and wondering if it is worth moving both the css and js.

3.0.0-rc1 is on testing, it should be great if you can install
https://github.com/REditorSupport/vscode-R/releases/tag/latest
and let me know if everything is working as intended.

For me Copying jquery.json-viewer.js rather than jquery.json-viewer.css from dist/resources/json-viewer/ up to dist/resources/ restores functionality works... This problem has remained unresolved for a long time, since a time I cannot remember. Thankfully found this solution here through ChatGPT...

This should be addressed by PR #1741 with a new list viewer design.
