Cursor IDE
I am trying to install Inspect AI - Visual Studio Marketplace
When I do so, Cursor hangs on “Installing” and the installation never finishes. When I open up Developer Tools and look at the network tab, I see that Cursor is repeatedly making POST requests to https://marketplace.cursorapi.com/_apis/public/gallery/extensionquery .
This extension installs fine in VSCode. It also installs fine on my coworker’s Cursor instance (not sure how his env is different).
Open the Extensions View, type “inspect-ai” in the search, install the first result.
It installs.
MacOS
Version: 2.3.35
Sometimes - I can sometimes use Cursor

Hey, thanks for the report. This looks like a client-side bug, not a network issue.
I passed the info to the team to investigate. If you can, please check the “Response” tab in DevTools for one of those requests and paste it here. It’ll help us understand what exactly the server is returning.

Hi @deanrie
I’m following up on the cursor extension installation freeze issue. Do we have any updates or a tentative timeline for when a permanent fix will be released?
Thanks!

I managed to install the package manually via f1 > “install from vsix”
