JSON auto-completion not working

Describe the Bug

Code autocompletion doesn’t work in Cursor. I’m not talking about AI suggestions, but the standard code completion feature.

Steps to Reproduce

Open a json file that should support autocompletion, such as tsconfig or a JSON with a $schema field.
Trigger autocompletion by pressing CTRL+space.

Expected Behavior

It should show an inline dropdown menu with the avaialble options.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Check if you have enabled this.

thank you that worked, although it’s weird is not enabled by default!
