Why Does JSON.stringify Fail to Stringify Error Objects?

Can't Stringify Errors with JSON.stringify?

In this scenario, it was observed that native Error objects cannot be directly stringified using JSON.stringify. When attempted, it produces an empty object.

Why This Occurs:

The properties of an Error object have an enumerable attribute set to false. This prevents JSON.stringify from accessing these properties, resulting in an empty object.

Workaround:

To bypass this issue, one can use the following workaround:

JSON.stringify(err, Object.getOwnPropertyNames(err))

This approach explicitly specifies the properties of the Error object to be included in the stringification process.
