Is it not possible to stringify an Error using JSON.stringify?

Question

Reproducing the problem

I\'m running into an issue when trying to pass error messages around using web sockets. I can replicate the issue I am facing using J

Answer 1

Make it serializable

// example error
let err = new Error('I errored')

// one liner converting Error into regular object that can be stringified
err = Object.getOwnPropertyNames(err).reduce((acc, key) => { acc[key] = err[key]; return acc; }, {})

If you want to send this object from child process, worker or though the network there's no need to stringify. It will be automatically stringified and parsed like any other normal object
