Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

While working with Jupyter Notebooks, Cursor can no longer generate more than two lines of code. Previously I was able to prompt Ctrl+K inside a python cell and instruct about the code, which I wanted to be generated. Now it is stuck up to two lines.

Steps to Reproduce

  1. Create an Jupyter notebook .ipynb file
  2. In a code cell prompt for a code generation (i.e.Ctrl+K and instruct to create a Fibonacci sequence)
  3. Observe it generating two lines and
  4. Display a Generating… message

Expected Behavior

Generate the requested code in the cell I am working on

Hey @Peio_Popov

Thanks for reporting this. I can reproduce this when I run Cmd+K without highlighting any text first.

Obviously not the intended behavior. I’ll report this. :folded_hands:

Also experiencing this. I noticed it first in a notebook, but it’s happening even on non-notebook files; was able to reproduce on a blank text file in an empty new project. I’ve been able to work around it for now by inserting a blank comment line and highlighting that before hitting cmd+k.
