Repro Steps:

  1. Install Visual Studio Codespaces extension -> Connect to a codespace -> Install the Function extension in the codespace.
  2. Create a new python project with "HTTP trigger" -> Debug.
  3. Expand the Local Project tree view and right click on the function -> Select "Execute Function Now..." -> Delete the default request body -> Press enter.

This repros for me without Codespaces and the important part is that it only happens if you delete the default request body. The other languages probably just have more error-checking in the default template than Python 🤷‍♂️ Since this works fine if you use the default request body, will close as "wont-fix"
