Illegal Value for primitive when trying to parse the json data

Question

I am facing the issue like "Illegal Value for primitive" when trying to parse the json data.Below is the Json Response which i get from a service.

[{"revenue": {}, "emails": [{"grade": "A+", "type": "info", "email": "massimo.cavalleri@kuldat.com"}, {"grade": "B", "type": "info", "email": "jacopo.serafin@kuldat.com"}, {"grade": "B", "type": "info", "email": "simone.marzola@kuldat.com"}], "lead_enrichment_date": "2016-01-27", "name": {"raw": "Kuldat sr.l", "formatted": "Kuldat s.r.l.", "business_type": "", "business_alias": "Kuldat", "business_name": ""}, "year_of_establishment": 0, "industry": {"codes": [], "raw": ["INFOANDTECHSERV"]}, "size": {}, "ranking": {"delta": -332533, "phone": 3, "social": 5, "value": 5, "email": 92}, "automation": [], "enrichment_date": "2016-01-27", "country": "IT", "leads": [{"seniority": {"month": 0, "year": 0, "raw": ""}, "name": "Massimo Cavalleri", "current": true, "status": "checked", "role": "developer", "links": [{"contacts": 0, "validated": true, "source": "linkedin", "url": "https://it.linkedin.com/in/massimo-cavalleri-14a7a121"}]}, {"seniority": {"month": 0, "year": 0, "raw": ""}, "name": "Simone Marzola", "current": true, "status": "checked", "role": "CTO", "links": [{"contacts": 0, "validated": true, "source": "linkedin", "url": "https://it.linkedin.com/in/marzolasimone"}]}], "feedback": null, "tax_id": {"formatted": "IT03513190987", "raw": "03513190987"}, "websites": ["http://www.kuldat.com"], "description": [{"validated": true, "language": "en", "source": "", "text": "kuldat test"}, {"validated": true, "language": "it", "source": "", "text": "kuldat test"}], "phones": [{"raw": "02.35925100", "area_code": "02", "country": "IT", "country_code": 39, "number": "35925100", "description": "Milano", "formatted": "+390235925100"}], "address": {"location": [12.4975443, 41.888395], "formatted": "Via Trieste, 25, 25121, Brescia, BS, Italy", "details": {"icon": "https://maps.gstatic.com/mapfiles/place_api/icons/geocode-71.png", "permanently_closed": "", "url": "https://www.google.it/maps/place/Via+Trieste,+25,+25121+Brescia+BS/@45.5373451,10.223621,17z/data=!3m1!4b1!4m2!3m1!1s0x47817614394a84a7:0x540aadf97192856a", "name": "Via Trieste, 25", "place_id": "ChIJT5F8Q7hhLxMRgBE2qMxsvec", "website": "", "utc_offset": "", "rating": "", "international_phone_number": "", "vicinity": "Roma", "types": ["street_address"]}, "source": "gplaces", "raw": "25, Via Trieste, 25121, Brescia, BS, Italy"}, "links": [{"contacts": 0, "validated": true, "source": "paginegialle", "url": "http://www.paginegialle.it/kuldat"}, {"contacts": 0, "validated": false, "source": "website", "url": "http://www.kuldat.com"}], "id": "569f6d6fe4b0ccecd3ef1390"}]

And my parser class is like below

Can anyone figure me what exactly is i am missing. And why do we get that error. Thanks in Advance.

To parse a JSON into a class, you need to check below points first:

If you are using standard JSON.deserialize method you need to check that json should not have any key which is reserved key word in salesforce

Json must not have any key which is not of type string

If you are going to parse your json manually, you can have any valid json and parse it in your class varraible as per your need.

So if you want an easy solution and have rights to change the JSON, Please change the JSON so that you can simply parse it using JSON.Serialize method.

If you cant change the JSON you need to parse it manually like below

public class JSON2Apex {
    public static void consumeObject(JSONParser parser) {
        Integer depth = 0;
        do {
            JSONToken curr = parser.getCurrentToken();
            if (curr == JSONToken.START_OBJECT || 
                curr == JSONToken.START_ARRAY) {
                depth++;
            } else if (curr == JSONToken.END_OBJECT ||
                curr == JSONToken.END_ARRAY) {
                depth--;
            }
        } while (depth > 0 && parser.nextToken() != null);
    }

    public class Description {
        public Boolean validated {get;set;} 
        public String language {get;set;} 
        public String source {get;set;} 
        public String text {get;set;} 

        public Description(JSONParser parser) {
            while (parser.nextToken() != JSONToken.END_OBJECT) {
                if (parser.getCurrentToken() == JSONToken.FIELD_NAME) {
                    String text = parser.getText();
                    if (parser.nextToken() != JSONToken.VALUE_NULL) {
                        if (text == 'validated') {
                            validated = parser.getBooleanValue();
                        } else if (text == 'language') {
                            language = parser.getText();
