What problem are you trying to solve?

Run tests with Node.js 16.9.0 (nodejs/node#40011).

Two of them fail because V8 changed the error message when trying to read properties from null or undefined.

   103) Core _debug() outputs 500 on ext exception:
       actual expected
       "Cannot read propertiesproperty 'here' of null (reading 'here')"

Do you have a new or modified API suggestion to solve the problem?

Adapt the following assertions to support the new error message:

hapi/test/handler.js

Line 65 in c2107e9

console.error = function (...args) {

hapi/test/core.js

Line 338 in c2107e9

expect(event.error.message).to.equal('Cannot read property \'here\' of null');
