I have a class that reads a JSON obtained by a callout and it works fine but when I try to do the test class for it I get an error Malformed JSON: Expected '{' at the beginning of object

When I run de class, I see the JSON has this structure but it doesn't generate any error

Also in my code I have

List<Object> result; 
result = (List<Object>) JSON.deserializeUntyped(jsonresponse.getBody());

That's why when the class run it works fine, but I don't understand why I get the error why I run the testclass.

And my mock class

public HTTPResponse respond(HTTPRequest token){
    HttpResponse res = new HttpResponse();
    res.setHeader('Content-Type', 'application/json');
    return res;

    The json in your mock class is not valid. [{data}], otherData}] is what you have. There's an unmatched object and list terminator at the end. – Derek F May 19 at 22:55
