I have the following sample fragment of JSON I am trying to deserialize.

```
{
    "total": 2236,
    "issues": [{
        "id": "10142",
        "key": "ID-2",
        "fields": {
            "attachment": [{
                "id": "11132"
            }]
        }
    }]
}

```

I can deserialize the data up to id and key, but cannot deserialize attachments that is in fields. My attachment class is always null

Here's my code.

Response.java

```
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class Response {

    @JsonProperty
    private int total;

    @JsonProperty
    private List<Issue> issues; 
}

```

Issue.java

```
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class Issue {

    @JsonProperty
    private int id;

    @JsonProperty
    private String key;

    @JsonProperty
    private Fields fields;
}

```

Fields.java

```
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class Fields {

    @JsonProperty
    private Attachments attachment;
}

```

Attachments.java

```
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class Attachments {

    @JsonProperty
    private List<Attachment> attachment; 
}

```

Attachments.java

```
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class Attachment {

    @JsonProperty
    private String id;
}

```
