GitHub Gist not integrating properly into Notion – Need help!

I’m trying to integrate an ipynb file into Notion using a GitHub Gist, but I’m getting the following message and the integration isn’t working properly. Has anyone else encountered this issue or know how to fix it? Any help would be appreciated!

Also, are there other methods to integrate the code and output of an ipynb file into Notion besides using Gist?
