Incorrect mutation to options object

[vjrngn]

Hey folks 👋🏼

I recently updated the package to 1.2.0 and looks like there's a bug that was introduced (link below)
https://github.com/nearform/fastify-auth0-verify/blob/master/index.js#L15C28-L15C28

My application sets the options.domain property but it is being deleted which is causing an bad behaviour.
Ideally, you would create a copy of the options object and leave user options untouched.

Didn't send a PR since this is a single line change. Happy to send a PR if that helps

Proposal:

function fastifyAuth0Verify(instance, options, done) {
  try {
    const optionsCopy = { ...options };
    let { domain, secret } = optionsCopy;

    if (domain) {
      delete optionsCopy.domain
   }
...
}

Thanks for catching this. What kind of bad behavior is the deletion of the domain property causing?

Closing for lack of response from the OP

Apologies for not getting back quick enough. We are using the options object in other part of our application - so passing it around on service start. This mutation caused a bug in a dependent service.

Can you send a PR please? I'll reopen the issue

Sure thing! Travelling at the moment and don't have access to a computer. Will raise one after I'm back home :)
