json Expected BEGIN_OBJECT but was STRING

Question

I have already read many answers about the same error, but nothing helps me.

Here I try to parse Json into my data class and get an error:

ErrorResponse bodyResponse = App.getGson().fromJson(responseString, ErrorResponse.class);

The error is : BEGIN_OBJECT but was STRING

This is my response string:

'{"title":"AccessCheckException","details":{"message":"User doesn't have authorized access."}}'

And Data class:

public class ErrorResponse {
    public String title;
    public Details details;

    public ErrorResponse() {
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public Details getDetails() {
        return details;
    }

    public void setDetails(Details details) {
        this.details = details;
    }}

What is wrong?

My Details class code (I reduced get/set to post it)

public class Details {
public String code;
public String msg;
public Attachment attachment;
public String message;
public String description;

public Details() {
}

}

Thanks in advance.

Is this simple quote at beginning in `'{"title":"` part of the response ? — PeterMmm, Dec 22 '17 at 12:29
So, strip it away. Your JSON starts with a quote and not with a `{`. — PeterMmm, Dec 22 '17 at 12:32
`'{"title":"AccessCheckException","details":{"message":"User doesn't have authorized access."}}'` is clearly not a valid JSON (due to `'` in the beginning and ending) — Vladyslav Matviienko, Dec 22 '17 at 12:36

Try this

ErrorResponse.java is mismatch with your json

    public class ErrorResponse {

    @SerializedName("title")
    @Expose
    private String title;
    @SerializedName("details")
    @Expose
    private Details details;

    public String getTitle() {
    return title;
    }

    public void setTitle(String title) {
    this.title = title;
    }

    public Details getDetails() {
    return details;
    }

    public void setDetails(Details details) {
    this.details = details;
    }

    public class Details {

    @SerializedName("message")
    @Expose
    private String message;

    public String getMessage() {
    return message;
    }

    public void setMessage(String message) {
    this.message = message;
    }

    }

    }
