![]() ![]() With Airbrake Error and Performance Monitoring, you can skip the logs and go straight to the line of broken code resulting in the JSON Parse error. The jsondecode () function takes a JSON-encoded string as its first parameter and parses it into a PHP variable. The first way to find a JSON Parse error is to go through your logs, but when you're dealing with hundreds, if not thousands, of lines of code, it can be difficult to find that one line of broken code. To dive even deeper into understanding how your applications deal with JavaScript Errors, check out the revolutionary Airbrake JavaScript error tracking tool for real-time alerts and instantaneous insight into what went wrong with your JavaScript code. Synta圎rror: JSON.parse: unexpected non-whitespace character after JSON data An empty PHP string or value that after casting to string is an empty string (NULL, FALSE) results in JSON syntax error. Synta圎rror: JSON.parse: unexpected character The basic structure of JSON consists of objects, which are sets of string: value pairs surrounded by curly braces: ' JavaScript Object Notation, better known as JSON, is a human-readable text format, commonly used to transfer data across the web. While most developers are probably intimately familiar with JSON and the proper formatting syntax it requires, it doesn't hurt to briefly review it ourselves, to better understand some common causes of the JSON Parse error in JavaScript. The JSON Parse error is a specific type of Synta圎rror object. JSONERRORINVALIDPROPERTYNAME ( int ) A key starting with u0000 character was in the string passed to jsondecode () when decoding a JSON object into a PHP object.The Synta圎rror object is inherited from the Error object.All JavaScript error objects are descendants of the Error object, or an inherited object therein.In this article, we'll dig deeper into where JSON Parse errors sit in the JavaScript error hierarchy, as well as when it might appear and how to handle it when it does. The JSON Parse error, as the name implies, surfaces when using the JSON.parse() method that fails to pass valid JSON as an argument. Traveling deftly through to the next item in our JavaScript Error Handling series, today we're taking a hard look at the JSON Parse error.
