invoking hapi.auth.verify does not execute the custom verify function

The following issue was discovered while troubleshooting the behavior identified in https://github.com/hapijs/nes/issues/292

I have a hapi server implementation which leverages hapi-auth-jwt2 as the default auth strategy. In this auth strategy, I have configured a custom verify function

I take all the defaults when configuring the plugin

{
    plugin: require("hapi-auth-jwt2"),
}

configuration when defining the strategy

await this.server.auth.strategy("jwt", "jwt", {
  verify: async (decoded: IDecodedToken, request: Request) => {
    // custom logic here
  },
  tokenType: "bearer",
  complete: true,
});
this.server.auth.default("jwt");

as part of the auth interface provided by the hapi server a verify method exists. hapi nes and presumably other libraries rely on this interface to verify authentication. https://github.com/hapijs/hapi/blob/master/lib/auth.js#L100

this method finds the auth strategy. If the auth stategy defined a verify method like hapi-auth-jwt2 does the verify method will be invoked https://github.com/hapijs/hapi/blob/master/lib/auth.js#L120

In the case of hapi-auth-jwt2 the invocation of this verify method calls https://github.com/dwyl/hapi-auth-jwt2/blob/master/lib/index.js#L295

This method does some default verification of JWT which probably works perfectly if you are not using a customVerify function. In my case my customVerify function does not leverage a public key for verification and as a result this method is unable to verify the provided jwt token. As a result the secret or public key must be provided is thrown.

I think I expect the verify function defined in https://github.com/dwyl/hapi-auth-jwt2/blob/master/lib/index.js#L295 to execute options.verify if provided.

maybe something like

verify: async function(auth) {
   const token = auth.artifacts;
   const decoded = JWT.decode(token, {
     complete: options.complete || false,
   });
   if (options.verify) {
     // verify using the provided function
     options.verify(decoded, /*not sure what to do about request*/);
   } else {
      const { keys } = await internals.getKeys(decoded, options);
      internals.verifyJwt(token, keys, options);
   }
},
