We do see an error between hono and @mswjs/interceptors with our requests. Here is the full stack trace which shows the error:

Somehow the inferRawHeaders function seems to return undefined instead of an empty iterable.

Hi, @KnisterPeter. Can you please submit a reproduction repo for this? I will take a look then. Thanks.
