How to Debug 'invalid character 'b' looking for beginning of value' Errors in Sakura JSON Responses?

Invalid JSON Response in Sakura Request

The error "invalid character 'b' looking for beginning of value" occurs when attempting to post JSON with an XML message inside, resulting in an invalid JSON format.

The issue lies in the Unmarshal function, as the server response is not in the expected JSON format. To handle this error, consider implementing the following debugging code:

err := json.Unmarshal(resBody, v)
if err != nil {
    log.Printf("error decoding sakura response: %v", err)
    if e, ok := err.(*json.SyntaxError); ok {
        log.Printf("syntax error at byte offset %d", e.Offset)
    }
    log.Printf("sakura response: %q", resBody)
    return err
}

This code provides additional details about the error, including the offset of the syntax error and the raw server response. It allows for easier debugging and identification of the problematic content.
