Error: "Cannot read property 'source.fixAll.eslint' of null"

[andrao]

This issue has come up with the latest version – 2.1.3:

I reckon it's caused by the new CodeActionsOnSave.isExplicitlyDisabled() function here: 5d3bc85#diff-bc3c0f2fe3aca9ddbe96347ffb00641eR466-R471, which doesn't account for the case where setting is null.

Through no deliberate action of my own, my User-level settings were updated to include:

{
   // ...
   "editor.codeActionsOnSave": null
}

Again I'm unsure as to why this happened – it wasn't a manual edit. I am indeed told that null is an invalid value when viewing my settings file:

May be common enough to warrant a fix.

Issue is resolved by reverting to 2.1.2.
