JavaScript-file is lacking in downloaded notebook for pytorch

Installed version miniconda:
conda/22.11.1 requests/2.28.1 CPython/3.10.8 Linux/5.15.0-56-generic ubuntu/22.04.1 glibc/2.35
installed environment d2l: 1.0.0b.
When I start the jupyter notebook locally and open index.ipynb I get an error:
404 GET /static/components/codemirror/mode/eval_rst/eval_rst.js?v=20230106155751 ( 18.340000ms
Does anyone know. where I can get this file (eval_rst.js). It is obviosly necessary for rendering references and such.
