Error 'TypeError: Cannot read property 'type' of undefined' in 1.2.2 version

[ppietruszewski]

Hello
I've tried upgrade contentful-resolve-response from version 1.1.4 to 1.2.2 and I get an error in console: TypeError: Cannot read property 'type' of undefined
I get response from contentful like that:
{ "sys": { "type": "Array" }, "total": 1, "skip": 0, "limit": 100, "items": [ { "fields": { "internalTitle": "Page", "slug": "b", "title": "B", "description": "test", "metaTitle": "B", "metaDescription": "" } } ] }
I think the problem is in lines:
https://github.com/contentful/contentful-resolve-response/blob/master/index.js#L120
and
https://github.com/contentful/contentful-resolve-response/blob/master/index.js#L122
My response responseClone.items doesn't have sys key so it will be undefined.
Can you check it?
In old version, everything works perfectly.

I also experience this issue after upgrading, in IE11 only. Previously this package worked fine in IE. Would love to see this resolved!

I'm also having this issue when doing a select query on the CDA

[janro1]

is this package/code still used? 2 years and the issue is still open, not even a comment?

btw, this additional filter fixes it for me:

    allEntries.filter(entity => !!entity.sys).map(entity => {
      return [makeLookupKey(entity.sys), entity];
    })
