Keybindings.json - cannot read property length of undefined

1. Open keybindings.json
2. Do some modifications -> notice exception in dev tools

TypeError: Cannot read property 'length' of undefined

In case you can not repro, here are the contents of my keybindings.json at the time of the exception

// Place your key bindings in this file to overwrite the defaults
[
  
{
    "key": "cmd+t",
    "command": "workbench.action.files.newUntitledFile",
    "when": "watchExpressionsFocused"
},
{
    "key": "cmd+g",
    "command": "workbench.action.tasks.terminate"
},
{
    "command": "workbench.files.action.collapseExplorerFolders",
    "key": ""
}

]
