Failed to find the kernel wolframscript in configurations. A kernel must contain a "command" field.

[giammi56]

On the deb version of VS code, the kernel cannot run because the "command" is not found, although it is in the .json file.

The configuration file looks okay. The error message is a bit misleading, since it can be the case that the extension did not find wolframLanguageNotebook.kernel.configurations at all, e.g. when this entry is in the Workspace settings (instead of User settings). I suggest that you may remove kernel configurations from all the settings, add the kernel from the prompt by the extension and see if it works.
