    ]
]

The URL: https://en.wikipedia.org/w/api.php?action=opensearch&search=Computer&format=json

My model:

import lombok.Data;

@Data
public class OpensearchResponse {

    String searchTerm;

    String[] possibilities;

    String[] empty;

    String[] references;
    
}

When i try to map the json respone like so:

var opensearchResponse = gson.fromJson(jsonResponse, OpensearchResponse.class);

I get this error

Exception in thread "main" com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $

I suspect my data structure is very wrong. But what exactly?
