Since Release 1.0.0 Symbol field handling is different for empty strings

[dlitvakb]

Observed on our marketing-website when transitioning from 0.8 to 1.1.

Tests still need to be created around this.

This has been tested with a pristine space with 3 symbol fields, one filled, one empty (via CMA), one nil. All 3 checks properly passed.

[3] pry(main)> client.entries.first
=> #<Contentful::DynamicEntry[test]: @fields={:name=>"Test", :empty=>""} @sys={:space=>#<Contentful::Link: @sys={:type=>"Link", :linkType=>"Space", :id=>"8jbbayggj9gj"}>, :id=>"3vuP7wtireIWM2WO2oiw4u", :type=>"Entry", :createdAt=>#<DateTime: 2017-01-02T20:07:37+00:00 ((2457756j,72457s,872000000n),+0s,2299161j)>, :updatedAt=>#<DateTime: 2017-01-02T20:15:48+00:00 ((2457756j,72948s,450000000n),+0s,2299161j)>, :revision=>2, :contentType=>#<Contentful::Link: @sys={:type=>"Link", :linkType=>"ContentType", :id=>"test"}>, :locale=>"en-US"}>
[4] pry(main)> client.entries.first.nil
=> nil
[5] pry(main)> client.entries.first.empty
=> ""
[6] pry(main)> client.entries.first.name
=> "Test"

Awaiting on more input from the marketing team to pinpoint their issue.

Looking at your test entry it looks like this (from the CDA)

{
  "sys": {
    "space": {
      "sys": {
        "type": "Link",
        "linkType": "Space",
        "id": "8jbbayggj9gj"
      }
    },
    "id": "3vuP7wtireIWM2WO2oiw4u",
    "type": "Entry",
    "createdAt": "2017-01-02T20:07:37.872Z",
    "updatedAt": "2017-01-02T20:15:48.450Z",
    "revision": 2,
    "contentType": {
      "sys": {
        "type": "Link",
        "linkType": "ContentType",
        "id": "test"
      }
    },
    "locale": "en-US"
  },
  "fields": {
    "name": "Test",
    "empty": ""
  }
}

However in the marketing website the field with issues looks like this

{
  "oldFileName": null,
}

Note that the value is a literal null.
