Failed to parse the JSON document: Request successfully return 200 response but response body isn't printed in Log file

Question

I got an exception with validating "status": "OK" in the response body of the DeletePlace request. Request is successful with 200 status code but there is no response body in the log file. Console error is pointing to the Utils line#47. Below is the code & screenshot of the error console pointing error to: enter image description here

package resources;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintStream;
import java.util.Properties;

import io.restassured.RestAssured;
import io.restassured.builder.RequestSpecBuilder;

import io.restassured.specification.RequestSpecification;

public class Utils {
    
    public static RequestSpecification req;
    public RequestSpecification requestSpecification() throws IOException
    {
        if (req==null)
        {
        PrintStream log = new PrintStream(new FileOutputStream("logging.txt"));
        req = new RequestSpecBuilder().setBaseUri(getGlobalValue("baseUrl")).addQueryParam("key", "qaclick123")
                .addFilter(RequestLoggingFilter.logRequestTo(log))
                .addFilter(ResponseLoggingFilter.logResponseTo(log))
        .setContentType(ContentType.JSON).build();
        return req;
        }
        return req;
    }
    
    public static String getGlobalValue(String key) throws IOException
    {
        Properties prop = new Properties();
        FileInputStream fis = new FileInputStream("E:\\Eclipse-Workspace\\RestAssuredAPIFramework\\src\\test\\java\\resources\\global.properties");
        prop.load(fis);
        return prop.getProperty(key);
    }
    
    public String getJsonPath(Response response, String key)
    {
        String resp = response.asString();
        JsonPath js = new JsonPath(resp);
        return js.get(key).toString(); //Error line
    }

}

Please help me out and let me know if any other information is required.

I've tried creating getJsonPath method again and all possible fixes I got from various articles but not able to resolved this. I'm expecting the test to execute without any error.

i recommend you to use org.springframework.core.io.Resource to get your properties, like this:

@Value(value = "classpath:your_file.json")
private Resource resource;

after you got your file, try to mapping with:

public static Map<String, Object> jsonToMap(String json) {
    try {
        final ObjectMapper mapper = new ObjectMapper();
        return mapper.readValue(json, new TypeReference<>(){});
    }catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}
