TypeError: Converting circular structure to JSON occurs when you try to reference your variable name within the JSON object.
var mycar ={}mycar.a = mycarJSON.stringify(mycar)
The code above will give an error since JSON.stringify
is unable to convert such structures. This also happens to DOM nodes with circular references.
Try to remove any circular dependencies that have been created in the code.
You can use the flatted package to solve the issue. Take a look at the example code given below:
const {parse, stringify} = require('flatted/cjs');const mycar = {};mycar.a = mycar;stringify(mycar);console.log(mycar)
At times, printing a value that has already been referenced might create circular dependency. However, if you remove such print statements, and the code should work.
