When sending a POST request and using angular.toJson on the payload, I encounter an error.
angular.js:12609 TypeError: Converting circular structure to JSON at JSON.stringify () at Object.db [as toJson] (http://localhost:8080/adminconsole/lib/bower_components/angular/angular.modified.min.js?_1553818615062:15:433)
Can anyone explain why this is happening?
Thank you in advance.
When working with JavaScript objects that contain circular references, it is not possible to serialize them using a standard JSON.stringify method. Here's an example:
Take a look at the following code snippet:
a = { name: 'Groucho' };
b = { name: 'Harpo', sibling: a };
a.sibling = b;
If you try to stringify object `a`, you will encounter an error like this:
TypeError: Converting circular structure to JSON
In such cases, you can create a custom serializer function that can detect and handle circular references appropriately. Fortunately, there are existing solutions available for this issue, such as https://github.com/WebReflection/circular-json.
Once you implement a custom serializer, the result for the above example would be:
{"name":"Groucho","sibling":{"name":"Harpo","sibling":"[Circular ~]"}}Notice how `[Circular ~]` denotes the path to the referenced object. In more complex structures, you might see something like `[Circular ~.rows.1]`.
