Getting Error in Azure Logic Apps in HTTP POST:- "BadRequest. Http request failed: the content was not a valid JSON."

Question

I have created a Logic App in Azure which uses HTTP Action Connector to POST request to a REST API.

The JSON body of this request looks like below:-

{
            "id": 40,
            "salutation": "Mr",
            "firstName": "Smith",
            "lastName": "Jack",
            "ageRange": "18-20",
            "gender": "male",
            "emailAddress": "atet4gsg@gmail.com",
            "phone": "3532523523",
            "phoneType": "mobile",
            "addressStreet": "1234",
            "addressCity": "gagdgd",
            "addressCounty": "gadgg",
            "addressCountry": "UK",
            "addressPostcode": "235dgds",
            "preferredContactMethod": "email",
            "leadType": "sales",
            "leadForm": "brochure",
            "dealerId": 1111,
            "dealerDepartment": "New Vehicle Sales",
            "externalSalepersonName": "3532532",
            "leadCurrency": "GBP",
            "leadMin": 1000,
            "leadMax": 150000,
            "leadStatus": "New",
            "interestInAccessories": "yes",
            "interestInFinance": "yes",
            "interestInInsurance": "yes",
            "interestInPurchase": "yes",
            "comments": "Test",
            "vehicleModelYear": 2019,
            "vehicleBodyStyle": "saloon",
            "vehicleEngineType": 2,
            "vehicleFuelType": "petrol",
            "transmission": "manual",
            "exteriorColour": "Brown",
            "interiorColour": "Brown",
            "make": "2019",
            "modelDescription": "A-Class",
            "modelYear": 2019,
            "vin": "353253",
            "registrationNumber": "2532532532",
            "odometerReading": 53,
            "serviceDate": "2019-12-04",
            "price": 53253,
            "vinVerified": "no",
            "sentToPOS": "no"
        }

It initially worked for me but now somehow I have started getting an error as "BadRequest. Http request failed: the content was not a valid JSON."

Please help if anyone has any idea about this issue.

Answer 1

This issue has been resolved. The problem was with the API I was requesting was not returning the response in the valid json format. Hence, logic app was failing while formatting the HTTP response. Thank you both for your replies.
