TypeScript types no longer work

[cerwind (Charlie)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Since updating to Cursor 2.0 typescript types no longer work,

Additionally, when I hold CMD and Click on a function I’m no longer taken to that function/definition but I suspect it’s a downstream issue of TypeScript not working

Steps to Reproduce

  const handleClick = (test: string) => {
   console.log(test)
  };

  handleClick(1);

The above code is no longer flagged as invalid typescript.

Expected Behavior

I should have a hint telling me the argument is a number and should be a string

Operating System

MacOS

Does this stop you from using Cursor

No - Cursor works, but with this issue

I have the same problem too. Please advise.

Hey, which version of Cursor are you using? This issue should be fixed in version 2.0.38.

[Josh_Chen]

Version: 2.0.54 (Universal), and i’m using Intel Macbook too

[deanrie]

Thanks for confirming you’re on 2.0.54 on an Intel Mac. That’s unexpected, since the SIGTRAP crash in 2.0.34 should be fixed in newer versions.

Please share:

• Output panel logs: View > Output > select “TypeScript” in the dropdown and copy any errors
• Developer Console errors: Help > Toggle Developer Tools > Console tab and look for any red errors

This will help us tell if it’s a regression or a different issue. Let me know what you find!

Thanks for the logs. I can see TypeScript language server errors in the screenshots. This is unexpected because the SIGTRAP crash from v2.0.34 should be fixed in v2.0.54.

Regarding the “TypeScript Native” extension: it seems to be in an inconsistent state - the Output shows “disabled,” but the extension appears enabled. Try:

• CMD/CTRL+Shift+P → search “Enable TypeScript Native Preview (Experimental)” and run it
• Open a TypeScript file and check if types work

If that doesn’t help, temporarily disable Native Preview to use the standard TypeScript server:

• Extensions → TypeScript (Native Preview) → “Disable”
• Verify @builtin typescript “TypeScript and JavaScript Language Features” is enabled
• Reload Cursor

Either option should work—pick the one that gives you working TypeScript. Let me know what helped.

Enable TypeScript Native Preview (Experimental)

Thanks for the detail steps!

I ran the it, but it doesn’t work.

I also tried to disable TypeScript Native Preview (Experimental), and enabled the JavaScript and TypeScript Nightly, but it doesn’t work neither.

[deanrie]

Thanks for the Developer Console logs.

I still need the TypeScript Output panel logs to see why TypeScript isn’t working:

View > Output > select “TypeScript” in the dropdown > copy all text and share here

Also, please try a quick check:

• Test without extensions: run cursor --disable-extensions from the terminal, open your project, and test TypeScript

The TypeScript Output logs will show exactly what’s crashing the language server. Let me know what you find.
