Errors when using notebook.nvim with lunarvim

## Description
i have added the plugin to `~/.config/lvim/config.lua`:
```
lvim.plugins = {
  {
    "meatballs/notebook.nvim",
    config = function()
      require("notebook")
    end
  },
}
```
I run :PackerUpdate to update plugins with success.

When i try to open an existing notebook
```
lvim jupyter_workflow.ipynb
```

i get the following error:
```
Error detected while processing BufReadPost Autocommands for "*.ipynb":

The notebook opens in lunarvim as json:
