l: this still doesn't guarantee that nextHopProtocol is a string - at the same time checking whether the key exists is probably enough

yeah, I figured the same.. I mean these are browser APIs, I think if this exists it will be a string, this is more to make sure this is not some other type of resource... IMHO we can do
- Just check existence (current code)
- Check existence +
typeof entry.nextHopProtocol === 'string - Only check type - requires type cast (which is fine I guess)
typeof (entry as PerformanceResourceTiming).nextHopProtocol === 'string

This removes a type cast for the performance observer and actually adds some guards to make sure we do not run into cases where a property we expect to exist does not exist.
It seems we sometimes ran into cases where
nextHopProtocolwould beundefined, not a string, leading to https://github.com/getsentry/sentry-javascript/blob/develop/packages/tracing-internal/src/browser/request.ts#L202 failing.I now specifically check for the existence of this property, as well as also adding a default for all the time based stuff (0) to ensure these also work in the case one of the fields does not exist (instead of checking for existence of all of them).
