Cannot edit response object - Object frozen

[iPOiZN]

Hi, I have the following code:
const GetChatsQuery = gql query($withBlocked: Boolean) { userChats(withBlocked: $withBlocked) { ${ GetChatGraphQL(10) } } };

` return this.apollo.query({
    query: GetChatsQuery,
    variables: {
        withBlocked: withBlocked
    }
}).map(res => {
    let response = <GetChatsResponse>res.data;
    // I get here the error
    response.userChats[0].messages.push(null);
    return response.userChats;
})`

The thing is that I'm getting an error on the push method:

Cannot add property 2, object is not extensible

As I understood from the internet it means that the object is frozen (Object.freeze).
Have anyone had that problem before? how can I solve it?

Hi, yes I had the same problem, solved it by creating a copy of the result JSON.parse(JSON.stringify(res.data)). This won't be blocked. Kind of dirty, but I couldn't find a better solution. ;)
